Honda VTR250 '98+

#1 Unread post by Shorts »

This is my first bike and I'm finding it to be a forgivng, yet fun bike. The seat height is a hint on the tall side, 780mm. The Vtwin 250 is peppy and gives nice low end. It's a very smooth shifting bike and easy clutch. It would be nice if the handle bars came a little wider and open ended instead of closed. Risers make the seating position comfortable.


As per the Add info about your bike thread.

I think the VTR250 sold in the states was the baby Interceptor. Still a water cooled V-twin engine. In-board front disc brakes.
I would be the old, slow guy. Just let me know where you are going and I'll try to get there before you leave.

Yes.
The engine is almost exactly the same as in the new VTR and it is based on 1/2 of the original 500 Interceptor engine of 1984. The inboard brakes were only in '88 and '89. This is the 1990 VTR 250 we had kicking around our garage for years:

I do really dig the new mini-Monster VTR however.....

The VTR250 Interceptor was sold in the States from 88-90. It looks similar to the Ninja 250.


I have seen a picture or two of a 98+ model in the States, in particular a yellow one in Seattle. So, it seems they can be imported. These bikes currently sell in the UK, Australia, NZ, Spain and Japan.

VTR250 FACTBOOK

1982 May HONDA announcing VT250F which loads the water cooling 4 cycles DOHC 4 valves 90 degree V type 2 cylinder 249cm3 engine of the new design. The power unit which in torque full is superior in control characteristic was loaded onto the lightweight body, it was nimble and as for this motorcycle which actualizes light maneuverability, being original, functional beauty coupled with the styling which overflows, as for the entry rider and the woman rider even from from the first, it acquired support many expert riders, from the time became also traction part of quarter motorcycle boom.

 And' February of 84, the 2nd generation VT250F which improves output torque quality furthermore debuts. Later,' furthermore improving output characteristics in April of 86, to 3rd generation VT250F model change. After that although' VT250 SPADA,' as XELVIS repeating model change to October of 91 in November of 88, the VT250 series to adopt the method and needs of enjoying the motorcycle which is in the respective age, while in V twin engine of established reputation including maturing, you became familiar as a standard motorcycle of each age.
 In addition, with one side of evolution of such VT250 series, the power unit of V-[tsuin] was loaded onto the motorcycle of wide genre e.g., it is loaded onto also model such as VTZ250 and V-[tsuin] Magna of non cowl specification.

 Regarding the load sport model where until recently, absolute power efficiency was required today, in the times when method of enjoying the motorcycle has diversified more and more, the user which seeks the feeling efficiency such as the feeling good acceleration impression and beat impression of the engine is an increase tendency.
 Receiving the needs of these days, as for HONDA, as the new generation sou pass Potts model which loads the big V twin engine, fire storm (the European name: VTR1000F and the American name: Super hawk 996)' it announces in 96, the country from the first has acquired high appraisal even in the foreign country. In addition, this machine becoming the trigger, [teisutei] the movement which takes a second look V twin engine has happened gently the domestic automatic two wheels/lightly regarding the category of the two wheels.
 Furthermore' October of 97, in addition to the slim body which shows light maneuverability, torque full of maturing it referred exhibited to the original characteristic of the VT series which loads V twin engine, the VTR which adopts [pipotsutoresuhuremu] which actualizes the handling of new dimension of the fire storm transferring, as a new standard load sport of the bicycle in “32nd Tokyo motor show” lightly, it received the appraisal which is higher than many people.

 When and this time, this VTR is announced formally in the country, such as fuel economy and cost of maintenance is low price and adding the high cost performance characteristic where price you do not look at example in this class you think important portion of efficiency of the motorcycle lightly regarding two wheels which possess many merits class, is not just fashion especially vis-a-vis the people of the young rider, if you can feel the method of enjoying the motorcycle where the inner part is deep, you think e.g., vehicle inspection time is not required.

As “the satisfactory using selfishness where where urban district travelling which travels most at the time of the development of the VTR, for the people of the general user (40~60km/h) with it seriously considers the using selfishness, skill is achieved the rich torque impression in the low & middle rotary limits and the beat impression of the engine wide with 5 fast missions in the time of urban district travelling and toward in the usual limits and, you are not enthusiastic and you aim the enjoyment which it runs”, expressing “the enjoyment which is due to the blowing rising which does not have stress in winding and the high-speed travelling time runs in the sporty running and the high rotary territory” respectively in theme, all travellingIn condition, the power efficiency which can feel the enjoyment which it runs was requested.
 In addition after guaranteeing the satisfactory routing characteristic at the time of urban district travelling regarding maneuverability, you aimed toward the compatibility of light characteristic with winding and stability of the high-speed travelling time.

 Image of the customer who is supposed has supposed extensive user layer regardless of the degree of experience of the sex age motorcycle. Directing in the entry rider, the dry weight, 139kg ease of the routing low due to seat highly, in the expert rider you aimed toward the materialization conversion of the motorcycle which can enjoy power efficiency and operation efficiency, and feeling efficiency to total.

 And at the time of the concrete design, including also when idling simply not to be restricted to the pursuit of limited efficiency such as the highest fast highest output, skill doing V twin engine peculiar charm in all speed limits, it designated that it receives as important matter, the [pipotsutoresuhuremu] peculiarity which receives high appraisal with fire storm being light, pliant maneuverability and the torque impression of the engine, in addition, in 250cc class, in many riders, enjoying feature exhaust noise and the like, easily in the familiar using selfishness of every day, it designated that it receives as goal.

Image


At the time of the styling decision of the VTR, how proper, in keyword, current age seek “standard load sport of new age” from the motorcycle, aiming toward the materialization conversion of the motorcycle which satisfies the important matter where it pursues “personality” and calls “standard and personality and” is contrary you started development.

 When these days, you try looking at general consumption trend, it is truly removes the unnecessary element necessary mono to be required, price been cheap, it is good truly, if mono is not, you can see the tendency that it is not related to buying.
 There being these kind of age, it is not possible simply to call the motorcycle of the cheap making just of BASIC standard. It is the basis of the sport model, after filling up the element, “pleasure which is seen and the pleasure which rides”, very the kind of motorcycle where the life itself which has that motorcycle becomes pleasant, you thought that it is the standard load sport which is required from current age.

 As technique of the styling, while following the image of the fire storm which acquires already high support, you can enjoy to, as it makes the 250ccV twin sport which many riders, you tried the materialization conversion of the design which makes from the character of the VTR BE PROMINENT which you aim with the simple conversion which it is thorough.

 The steel make truss pipe frame which has popular simple [suinguamu] [pipotsutoresu] structure with fire storm was adopted to the basic framework, also pipe layout was thorough in the light impression of the VTR and method of showing the engine component adhered, adopted, best form such as size and piping layout of the frame pipe.

 At the time of the decision of proportion, it designated that you locate the mainframe as the center of mass, function such as seat size and loading characteristic necessity after holding down sufficiently, the fuel tank, the seat and the appearance part of the rear cowl and the like you are small to the utmost, show shortly as theme.
 Around the rear after giving one bodily sensation in the seat and the seat cowl, the underside was largely squeezed, gives the spirit as one lump, simple image of the whole body was emphasized by the fact that the seat rail of the frame is wrapped.
 In addition, in order not to become the impression where the part which becomes independent is arranged disjointedly, it seems that the seat and the seat cowl of this one image, pierce in the fuel tank and the engine which are connected by the mainframe stick, being simple mass concentrates, you tried bold design.

The curved surface and the edge were adopted to processing of detail, intentionally. The fuel tank although give the roundness in the line the rear, enlarging the projection of cross direction, insists exotic personality e.g., the cavity and the sharp line for escaping the steering wheel are expressed.

 In order to express high functionality, the prejudice which it is thorough even in the functional part was poured. As paint of the magnesium color is administered to each covers of the engine, it made color and the finishing which have texture of the material e.g., brake carry before & after per alumite processing is administered to the appearance aspect.

 In addition, the mainframe and the swing arm, the color tone of top [botomuburitsuji] and the step holder was standardized, the mainframe as a framework made the color ring of the fuel tank and the color scheme which makes from the mechanical impression of the engine be prominent.

 Furthermore, the front & rear wheel adopts the VTR private design of the new design which is considered in matching of light weight conversion and body appearance, it is light and the [supeshiyaritei] impression it has made 5 these spoke wheels of the Z letter section which overflows.

 You thought that in order even alone to receive sympathy in your many customers this time, as a standard load sport, also price is important functional part. Because the commodity charm which repaints former price image largely is actualized, to the usual method of keeping putting out added value with specification equipment as a technique of the engineering and styling design, “did not mean adding with the conception of opposite completely, it shaved and it advanced development with method of thinking, design which is dropped”.
 Concretely, plural functions were given to one part, by the fact that component score is reduced, a more rational constitution was actualized, the functional conscious design work which improves motorcycle original efficiency was done. The keyword, part less design was born from here.

 As for the styling of side view, although from the fuel tank which can give originality and the rich volume impression, to the rear cowl which tightens sharply as an appearance part by the fact that form is given, abolishing the side cover even in the seat section which is continued, it actualized the forum which is formed the styling.
 As for the step holder which is enlarged with the adoption of [pipotsutoresuhuremu], you divided the design element into the [pirionsutetsupu] section which is made the main step section and truss structure, showed visual, small Takasina rank you made the finished in addition as the mainframe by administering the paint of the same color.

Being simple, BASIC you prepared the color variation of 3 types which express the personality of the standard load sport VTR of the new generation respectively. In order to emphasize unique body work, graphics being able to meet, has made minimum.


Fourth silver metallic
The color ring of the new silver which produces the contrast of the shadow which adopts the metal frame which administers special coating, until recently is not. It is the image color which makes the sharp image of the VTR BE PROMINENT, produces the mechanical impression of the frame and the engine.

Image

Italian lead-lead
The italian lead-lead of the crimson which insists the exotic image of the VTR produces the light impression and enjoyment of light/write weight sport deeply in the bright sunlight.

Image

Black
As for the body color which blackout is done as the underside and furthermore it makes the black paint around the supplemental devices and the body be prominent, the charm where the VTR is condensed is expressed to the spirit 悍 at monotone.

Adopting water cooling 4 cycles DOHC 4 valves 90 degree V type 2 cylinder 249cm3 of maturing which shows the highest output of torque and 32ps/10,500rpm whose 2.4kgm/8,500rpm is thick to power unit. Without impairing the blowing rising impression at the time of high revolution, with the goal of the improvement of the torque impression in the low & middle rotary limits, flexible you aimed toward quality in all the rotary limits. Furthermore, as it improves the inertial mass of the flywheel substantially, coupled with the wide 5 fast conversion of gear ratio, it has made the power unit which can have enough the beat impression of V twin engine in all the rotary limits.
 In addition, it administers the Takasina rank finish to the left and right crankcase cover and the head cover, it has made the engine appearance whose material feeling is high.

Image

* Maturing the engine
 Adopting the water cooling 4 cycles DOHC 4 valves 90 degree V type 2 cylinder 249cm3 engine which over long time, repeated maturing to power unit is established reputation. This time, without impairing the blowing rising impression in the high rotary limits, in order to improve the torque impression in the low & middle rotary limits, as [shirindahetsudo] [intekupoto] form is modified, besides the fact that valve timing and the valve lift quantity of the inlet/outlet camshaft were modified, on inhalation side, the unequal long air funnel is adopted on the front/the rear.

In addition, in order to assure the decrease of the friction, as valve spring, to single spring is converted until recently from the double spring of the model, [kamuchiemu], assuring the decrease of mechanic sound, assuring the high improvement of efficiency of the engine and the improvement of silent characteristic, has administered maturing to detail e.g., you adopt the new model inverted tooth chain.
 Furthermore, besides the fact that form of the ACG flywheel was modified, inertial mass increased approximately 12%, the mission to wide 5 speed by the fact that it converts, the acceleration impression and the beat impression only of V twin engine have been expressed from former cross 6 speed.

 In addition this time, reduction of completion car number of articles and, the decrease of vehicle weight and in order the decrease of the mechanic transmitted sound with the improvement of rigidity to assure, the crankcase breather of the model was modified until recently to the head cover breather, the head cover new was designed attendant upon this.

* Inhalation system


 Inhalation system supplies the appropriate mixture always vis-a-vis the required inhalation quantity of the engine, has adopted linear the φ32mmVD type carburetor which actualizes the throttle response, combining with bulk. With this, it has been compatible the smooth blowing rising impression of the high rotary limits with the rich torque impression of the low & middle rotary limits.
In addition this time, the air funnel of the front and back cylinder by the fact that it sets to the length which is optimum to the combustion of the respective cylinder, combustion efficiency and improvement of fuel economy are assured.  It actualizes the fuel consumption rate which those results, 40.0km/L (60km/h fixed area travelling test value) with you say and is superior, goes hand in hand with the fuel tank capacity of 13L, raises the convenience at the time of long touring.

 The air housing guarantees the bulk of 6.1L, straight resistance is little by the fact that it arranges in the central upper part section of V type engine makes inhalation possible. This time, by the fact that internal constitution of the case is taken a second look, direct it actualizes the throttle response, handles in all the rotary limits and easiness and sport characteristic has been compatible.

 The reservoir tank of the [rajieta] chilled water which is arranged in the frame head pipe rear, functional other things as the original extra tank, has given, plural functions such as control function of the dynamical pressure influence by the fresh air vis-a-vis the air intake duct and partition function for being stabilized the carburetor temperature when travelling.

* Exhaust type
 Exhaust type in order to obtain the exhaust sound which utilizes the decrease and field sound feeling of vehicle weight, has adopted 2 into 1 mufflers of the simple pipe layout which adopts chamber less structure.
 At the time of the setting of exhaust system, V twin engine peculiarity without impairing the torque impression in the low & middle rotary limits and the blowing rising impression in the high rotary limits, are faithful to the field sound only, of V twin engine sound and the small feeling which it designated that the good beat impression is obtained as goal.
 Concretely, it adds the contraction to the pipe terminal of the gathering section of the exhaust pipe, the muffler section, length of the glass wool and the inner pipe, optimizes the arrangement of size and the separator, internal constitution adopting the bulk 3 room expansion types of 3.9L which is made possible limit simple and optimum structure. Until recently, although raising capacity and major diameter by comparison with the model, showing the output characteristics which you aim by the fact that it improves expansion ratio substantially, you hold down the unpleasant crack impression of high frequency and low you actualize the exhaust sound which emphasizes frequency sound.

Furthermore, as for the exhaust sound pressure after clearing harsh domestic noise 3rd gradual regulation, from low speed to high speed, the sound making which can be enjoyed even in all speed limits is administered.
 In the various sounds which concretely, occur from the whole vehicle, overpressure value in the feeling good usual speed limits is raised by holding down mechanical noise of the engine to minimum, for the rider, when riding in a car the exhaust noise which the rider hears is designated as strong ones.
In regard to these designs, you designed detail on the basis of the judgment with the feeling of the human e.g., it makes on the basis of the hearing of the rider who really is in the midst of travelling not to depend on only the test data due to meter measurement.

The mainframe designates the method of thinking the frame work of fire storm as the base, adopts the truss structure only the VTR by the steel pipe. In addition, the [suinguamupipotsuto] section in the crankcase of the engine volt/bolt it guarantees degree of freedom of setting by the fact that it turns on.
 At the time of the concrete design, as the high-tension steel is used in the section and light weight conversion is assured, proper strength rigid suppleness was set with CAE analysis, in the design which to the utmost is not wasteful, light weight compact frame work was actualized. Furthermore, the seat rail section makes another body volt/bolt on type, has considered even in maintenance characteristic. In addition, part less design is adopted and by the fact that multi-functionality of each part is assured, also maintenance characteristic of the ignition plug and the like has improved.

Image

Image


* Light weight conversion and the multi-functionality of the section which it is thorough
 In order this time, to achieve the light weight conversion which it is thorough, returning to starting point, it pierced part one one function from plan stage of the design and stuffed, it started styling design with the constitution which excludes the functional upper unnecessary part. As a result, the dry weight 139kg of most light weight in the former VT series was actualized.

The optimum and the lightweight part design with ■CAE analysis
 The frame, concerning important part such as swing arm and wheel, proper strength, it sets rigidity and suppleness to the section with CAE analysis, optimizing pipe size, and the board thickness of the section in the design which to the utmost is not wasteful


* Minimization of the section board thickness with the frequent use of the high-tension steel material
 The head pipe gusset of the mainframe, the down tube, the rear tank mount stay, adopting the high-tension steel material for the rear bracket plate and the muffler stay etc

* Light weight conversion and the Takasina rank finish which volts/bolts are thorough
 In the VTR functional beauty is pursued to one one of volts/bolts. Concretely, socket volt/bolt is adopted in large diameter volt/bolt of the engine hanger and the like lightweight DR volt/bolt, concerning the place where it becomes an important point with respect to appearance in hollow flange volt/bolt and volt/bolt in, function of each volt/bolt, the Takasina rank finish of upper-class type level is adopted for the material, form and finishing etc.

* One type seat & seat cowl
 Being simple, while actualizing the light styling, in order to designate removal and re-installation as simpler ones, it has made the structure which removes and re-installs the seat and the rear cowl with one body. In addition, clearance of the seat and the rear cowl as much as possible it becomes possible with this, raises one bodily sensation around the rear on the styling to stuff.
 In addition, in loading the baggage it equips the rope hook in seat cowl rear lower part, and the step holder rear end from [pirionshito] puts on the rear cowl and it guarantees sufficient loading characteristic by designating the line as flat.

Image


* Being simple, around the step of the Takasina rank finish
 The step holder, as as the mainframe it makes aluminum die-cast make paint of the same color is administered, around the step has made Takasina rank specification e.g., also the main step arm makes aluminum die-cast make.
 In addition, as for the rear stop lamp switch of step holder side of the right side, you consider in appearance design, without impairing operativity it became possible to arrange completely on step holder reverse side.
 Chrome plating was administered to the brake pedal/the change pedal, Takasina rank material feeling the anti- characteristic which is superior was actualized.

* Being simple, around the step of the Takasina rank finish
 The step holder, as as the mainframe it makes aluminum die-cast make paint of the same color is administered, around the step has made Takasina rank specification e.g., also the main step arm makes aluminum die-cast make.
 In addition, as for the rear stop lamp switch of step holder side of the right side, you consider in appearance design, without impairing operativity it became possible to arrange completely on step holder reverse side.
 Chrome plating was administered to the brake pedal/the change pedal, Takasina rank material feeling the anti- characteristic which is superior was actualized.


Image

Furthermore, with light weight conversion, by the fact that it makes multi-functional, substantial reduction of number of articles became possible concerning each functional part.
・ The styling of the completely new side view where the side cover was abolished,
・ The seat sabot section and the layout which designates the seat cowl as portion of the rear fender
・ Fender and battery box, combined use conversion of Electrical equipment installation section and seat opener installation section
・ Multi-functionality of [rajieta] chilled water reservoir tank
・ In air housing ignition coil, centralization of installation of part such as main harness and carburetor air vent tube
・ Unification of seat sabot and rear cowl

“The lightness whose handling of the VTR, while succeeding the method of thinking the fire storm, is suitable in standard load sport and has response” it has been formed operation stability to theme, with completely new methodology.
 First, it forms the unit whose rigidity is high around the head pipe of the nosewheel and the mainframe, it connects to [pipotsutopureto] which installs around the rear wheel and the swing arm in the engine, forms another unit. And, has connected these two units, with only hanger volt/bolt of the left and right each 2 places which set optimum connection rigidity. As by the fact that suppleness of the frame operates this structure, light characteristic of the low-speed time is made to actualize, the engine whose mass is large catches the disturbance from the rear wheel the high-speed travelling time, is attenuated around the engine hanger, shows high stability by the fact that influence to nosewheel side is held down.
 In the VTR it utilizes the assembly of [pipotsutopureto] and the rear fork as the decisive element of operation stability. As for the installation of the [pipotsuto] section, through the bearing outside the color, you install the swing arm, place the step holder left and right outside, make [pipotsutoboruto] penetrate and have tightened.

Image


Dimension, in order to show the light characteristic at the low-speed time, by the fact that head pipe position is moved to the 31mm front /20mm lower part the crank center section of the engine as a standard, has raised the response at the time of the bank and the sense of relief of handling even in nimbleness. In addition, also the wheel base has converted 1,410mm and to short wheel base.
 Setting of frame rigidity as torsional rigidity is increased in order to obtain the ground load which is stabilized, seeking the light characteristic and suppleness of handling, lowers side rigidity.
 At the time of the setting of riding position, the light sport characteristic which is required from load sport and being calm it is compatible the using selfishness of every day, it set the sporty position whose degree of freedom is high.
 Generally, in the motorcycle of sporty position the entry user focusing on weight of handling of the low-speed travelling time was pointed out, but in the VTR it is feature of [pipotsutoresuhuremu], it is light at low speed, the light handling which utilizes the feature that stability increases at high speed, was actualized.
 In addition, it set steering wheel being cut off angle to left and right 35 degrees, went hand in hand with the wheel base of 1,410mm and actualized sufficient routing characteristic even in the urban district.

Image


* Front/rear suspension
 Front suspension guaranteed the stroke quantity of 130mm with inner tube diameter φ41mm, telescopic type of tapered free valve attaching is adopted, the ground impression at the time of riding comfort and sport travelling which have the filter with the software has been compatible at high dimension.
 One side the pickpocket it divides the axle conclusion section and, by the fact that rigidity is raised as a formula just, it has made the improvement of operation feeling contribute. In addition, it makes the private design because also the top/bottom bridge guarantees optimum rigidity, it shows the handling quality which is superior even under wide travelling conditions.
 As for rear suspension, in the separated compressed type damper section of the piston diameter φ40mm which has the axle travel of 120mm, H.M.A.S. You have adopted (the HONDA [maruchiakushiyon] system) combining. It has made the setting where also setting to piston speed all paid attention.

* Front/rear wheel
 The front/rear wheel expressed the personality of the VTR and made private design of 5 these spokes which assure matching the functional body design.
 Cross section of the spoke section to be large designated section modulus as setting possible Z letter type vis-a-vis I letter type and S letter type, assured the compatibility of rigidity and strength and light weight conversion, actualized class most lightweight level.
 Approximately as for the tire, as a standard load sport riding comfort and sport characteristic it is compatible, it adopts the tread pattern which is considered even in travelling at the time of the rainy weather. You consider tire size in circulation characteristic and the front 110/70- 1753 S, the rear 140/70- adopt 1766 S.

* Braking system
 You have adopted both the front & the rear, single carry of pin sliding type combining the semi metal pad which is superior in per control characteristic and durability and anti- characteristic.
 As you adopt the this carry per super lightweight small-sized bracket, contribute to the decrease of vehicle weight, it administers alumite color on the outside, it has made the finishing which has texture of the material.
 The front disk assured light weight conversion and new designed 5 pin floating disks of φ296mm×t4.5mm. This disk plate, while actualizing light weight conversion, in comparison with the model until recently, being simple, has designated the design of the spoke section as strong ones. In addition, the small diameter disk of φ220mm×t5mm is adopted to the rear disk plate.

* New model digital spark unit
 It is low, in order from revolution to high revolution, wide to obtain the engine quality which shows output characteristics at the entire area, in the VTR digital spark unit of new development is adopted, separate ignition timing setting possible independent ignition system is adopted in the front and back cylinder.
 This digital [supakuyunitsuto], when the CPU specifications to 16 bits by the fact that it converts, it increases memory capacity substantially from the former 8 bits, improved transaction of operation ability simultaneously substantially.
 With this, you could obtain optimum combustion in the respective cylinder, as for engine quality of the VTR compatibility of [hurekishibiritei] and the response which until recently exceed the model actualized.
 In addition, this unit achieves approximately 20% (this corporation ratio) miniaturization vis-a-vis former ignition unit, has contributed to the degree of freedom improvement of the completion car design.

* Light weight conversion of electrical part and centralization of mass
 As it arranges battery and digital [supakuyunitsuto] which have weight below the body center of gravity nearby seat, assures the centralization of mass, the harness where such as starter magne-switch heavy-current flows is designed to the utmost around, efficiency rise and weight reduction are assured.
 In addition, everything you install fuse box and digital [supakuyunitsuto] etc in the battery box, think one unit and have considered even in maintenance characteristic.
 Furthermore, the ignition coil was arranged in shortest distance vis-a-vis the ignition plug of the front & rear cylinder, by the fact that it wires with the ignition high tension cord, high improvement of efficiency and light weight conversion of ignition were actualized.

As for the headlight, in order to guarantee high visibility and suffering visibility even with nighttime travelling, adopting the large diameter headlight of φ180mm which equips the halogen sphere of 60w/55w. As the resin make lens which administers hard coat processing to polycarbonate is adopted for the lens, it has made around simple and the lightweight headlight e.g., also the headlight stay makes left and right division type type.
 In addition this time, main switch installation position is moved to the upper part in order to hold down steering inertia and headlight mount position is made the layout which is brought close to the utmost on the steering wheel rotary center.

Around the meter of small size light weight of new design
 Around the meter, the meter case of the round dial design which is superior in visibility when riding in a car new was designed. Form removes the excessive space, makes the functional speedometer case and the design which unifies the small-sized indicators, adopts the meter panel of the blue.
 As for this meter panel, as for letter and the graduation as visibility of daytime is raised by making white, nighttime, only the letter section while day and night showing the personality which is different, it raises visibility in blue area e.g., it radiates in orange with transmitted light.

In addition this time, the engine wide was designated as output characteristics and there is no tachometer by improving the flexibility in all the rotary limits, the running which can be enjoyed sufficiently actualized.
 As a result, the tachometer was not installed regarding the VTR, light weight conversion of steering system and design of the around simple cockpit actualized simultaneously.

* Adoption of small-sized self starter motor
 The self starter as coil major diameter from φ68.25mm to small diameter is converted to φ61.8mm by this time improving the magnetic force of the magnet substantially, until recently by comparison with the model, made the design which contributes to the small size light weight conversion of power unit e.g., weight approximately 360g is decreased.

You gotta love those "translations" you get from Japanese sites.
So what I think it is saying is that the VTR250 was around BEFORE the 500 min-ceptor that I thought that it was based on.....
.....now that I think about it, I believe that the 500 mini-ceptor might have been based on the 400cc V-Four that they had in Japan a year earlier as well. I guess time (and Shorts posting) may prove my fuzzy memories wrong on that one as well....
