2017 Honda CRF450RX on www.Totalmotorcycle.com
The ultimate off-road weapon...
When it comes to motocross, our new 2017 CRF450R is huge news this year.
But in the enduro, hare scrambles, and GNCC world, theres even bigger
news: Introducing the new 2017 Honda CRF450RX, the ultimate weapon for serious
off-road competitors. At its core, weve taken our new CRF450R and optimized
it for off-road racing. And not with just some new tires or graphics. Weve
done it the Honda waythe right way. And the results are, well, electrifying.
As a brand-new model, Honda's CRF450RX boasts most of the features of its motocross-directed sibling, but in a package that's designed for closed-course off-road riding and racing. Among the features that distinguish it from the CRF450R are a smoother ignition map and standard electric start (with kick-start backup), while chassis differences include off-road-focused suspension settings, a revised cylinder-head hanger and changed wheel hubs and axles. The CRF450RX also comes with off-road-appropriate components like a larger plastic fuel tank, forged-aluminum side stand, 18 inch rear rim and Dunlop Geomax AT81 tires, making it the ultimate weapon for events like those in the GNCC series.
On the 15th anniversary of Honda's original 450cc class four-stroke motocross model, Honda announces a revolutionary CRF450R that promises to be the most powerful, best-handling Honda motocross machine ever. Honda's no-compromises approach to designing and developing the new bike was intended to put it at the front of the pack in all areas of performance, resulting in what Honda is calling the "Absolute Holeshot."
Since its 2002 introduction, the CRF450R has earned an enviable racing pedigree, and the 2017 edition is the best yet, with superior technology and style. Riders know that the most important part of any motocross race is the start, and the new CRF450R Unicam® engine has been developed to achieve overwhelming performance in the first 100 feet of battle, offering increased power output but also allowing unparalleled traction. And while arriving to turn one first is significant, winning requires staying in front for the entire moto, which is why Honda engineers designed an all-new chassis with reduced weight and centralized mass. The result is a machine that is at once fast, reliable and forgiving, and that allows riders to more easily extract maximum performance, consistently turning low lap times while simultaneously taxing their bodies less.
In addition, Honda is offering a brand-new model, the CRF450RX, which is based on the 2017 CRF450R but with a number of differences that make it appropriate for closed-course off-road racing like the GNCC series. Like its motocross-focused sibling, the CRF450RX is designed for maximum agility and performance, offering owners superior power along with effortless handlingthe ideal woods-racing combination.
Honda also took the opportunity to announce the remainder of its 2017 model-year CRF competition dirt bike model line, including the CRF250R and CRF150R motocross bikes and CRF450X and CRF250X off-road motorcycles.
"We're very proud to introduce the milestone 2017 edition of Honda's
legendary CRF450R, as well as the brand-new CRF450RX," said Lee Edmunds,
Manager of Motorcycle Marketing Communications at American Honda. "Both
of these models are high-performance machines that represent the epitome of
dirt bike engineering. Over the years, each of the milestone CRF450R models
has been eagerly anticipated, and the 2017 version is the best yet. We can't
wait to see these models being piloted at the front of the pack by our factory
Team Honda HRC and Johnny Campbell Racing squads, our satellite teams, our
amateur racers and our customers."
How about Enduro?
Honda has an all-new, genuine competition-ready enduro machine in its off-road line up the CRF450RX. And it takes as its rock-solid base the engine and chassis package of the 17YM CRF450R Hondas totally new 450cc moto-crosser.
This makes it the perfect platform on which to build an enduro machine, giving the CRF450RX both the pure moto-cross DNA to deal with any special enduro stage and the confidence-inspiring competence to handle flat-out trails, challenging climbs and tight, tricky sections with ease.
The CRF450RX is something truly special, not just for Honda, but for the enduro world to ride and race. It looks different and feels different to the rest of the pack.
And, just like the new CRF450R, it is compellingly fast.
2017 Honda CRF450RX www.Totalmotorcycle.com Key Features
Electric and Kick Start
Talk about the best of both worlds: The new 2017 CRF450RX comes with both
a kick- and electric-starting system as standard equipment. Having both options
will ensure faster GNCC starts for the ultimate holeshot.
An 18-inch rear wheel is another indication of the CRF450RXs off-road
heritage. Whether its red Georgia clay, Florida loam, or Baja sand and
rocks, youre going to find this bike offers the performance you need.
Stopping for fuel in a race costs time. With the CRF450RXs 2.2-gallon
fuel tank, depending on the course and how much roost youre making everyone
else eat, its possible to make it through a three-hour enduro with just
one fuel stop.
This simple, handlebar-mounted button lets you dial in engine power delivery
character with a push of your thumb. Choose between Standard, Smooth, and
Aggressive, depending on course conditions.
Power to victory
The Unicam engine that powers both the CRF450RX and CRF450R has been radically improved for 2017, with more horsepower, more torque, and a higher rev limit. The RXs engine has special ignition mapping to suit the unique demands of cross-country and endurocross competition.New cylinder head
Completely new Unicam cylinder head design uses finger rocker arms, oval cross-section valve springs, bigger intake valves, and increased valve lift to boost horsepower and allow a higher rev limit.Improved combustion efficiency
By straightening the intake path, reducing valve angle, and revising both combustion chamber and piston shape, engineers were able to improve flow and increase compression ratio for an even bigger power boostBetter lubrication
A new scavenge pump system with no separate oil tank improves engine lubrication, reduces friction, and requires less oil for reduced overall engine weight.Programmed for power
The CRF450RXs Programmed Fuel Injection (PGM-FI) settings contribute to the engines strong low-end torque, remarkable top-end power and generous over-rev capability.Engine Mode Select button
