2016 Yamaha WR450F Review

2016 Yamaha WR450F on www.Totalmotorcycle.com

Extremely precise and nimble cornering and strong 450cc class power makes the all-new WR450F the best bike to race or just trail ride…


The all-new WR450F will prove to be a great enduro race bike as well as an aggressive trail bike for riders looking for modern technology and performance.

The all new WR450F utilizes many of the same features as our championship winning YZ450F. Yamaha’s engineers draw on the highest level of competition for inspiration & innovations. From engine design to suspension to exterior styling, the racing performance & presence of our YZ models can be found in our entire competition model lineup.

/// Power
The all new WR450F utilizes our latest championship winning YZ450F rearward slanted, reverse fuel injected engine design. Tuning has been revised to suit enduro style use. The new WR450F produces serious power for those riders who are serious about winning. And with our optional GYTR Power Tuner, the machine can be quickly “tuned” to suit current riding conditions. Click here for YZ Power Tuner suggested settings.

/// Frame
Compact “Bilateral Beam” aluminum frame centralizes mass for exceptional handling & manoeuverability, especially in tight technical situations. By centralizing mass, our engineers have produced a machine that feels and handles more like a 250. Add in the industry’s best & most “tune-able” suspension system and you have an unbeatable combination.

2016 Yamaha WR450F www.Totalmotorcycle.com Features and Benefits

•YZ450F based, “reversed” liquid-cooled, 450cc, DOHC, 4-valve (titanium), 4-stroke, single with fuel injection & electric starting. The engine has been tuned for excellent “ride-ability & controllability” delivering a broad, easy to use power band with excellent power characteristics.
• Rearward slanted, reversed cylinder design.
– rearward slant moves a significant amount of rotating weight toward the centre of the chassis
– rearward slanted design centralizes mass for excellent handling & a light feel
• “Reversed” engine design (FI system is front mounted, exhaust exits from rear of cylinder).
– FI throttle body & air box are front mounted, providing a straight intake path
– straight intake path into the cylinder, provides optimum fuel/ air flow for excellent power
– front mounted intake keeps fuel cooler since engine heat has less effect on incoming fuel (cooler fuel is more dense & increases power)
– design centralizes mass for light, agile handling
• Electric start with manual kick starter & auto decompression system. Unit can be re-started in any gear.
• There is no main ignition switch on this model.
– electric start button (RHS handlebar) activates the entire electrical system
– kill switch (LHS handlebar) if held for a few seconds shuts down entire electrical system
– design reduces weight
• Compact 4-valve cylinder head features a 12.5:1 compression ratio.
– titanium 37 mm intake valves & titanium 30.5 mm exhaust valves
– 4-valve design offers optimum flow for excellent power & torque
– compact combustion chamber design
• Lightweight titanium valves use load-reduced oval valve springs.

• Lightweight, ceramic composite coated aluminum cylinder.
– reduced weight- no sleeve or heavy liner- plating is sprayed directly on the aluminum block
– ceramic coating insures faster, more uniform heat dissipation
– coating enhances the thin film of oil between the cylinder & piston, reducing friction & increasing power
• Cylinder “cutaways” allow air “trapped” under the piston to enter a side chamber (or cutaway) to reduce horsepower-robbing “pumping losses.”
• The crankcase also utilizes cutaways to reduce “pumping losses”. The crankcase cutaways match the cutaways in the cylinder for maximum efficiency.
• Lightweight, short-skirt, forged aluminum piston.
– lightweight design means faster throttle response
– reduced mechanical vibration for excellent durability
– special coating on piston skirt reduces friction
• Piston oil cooler jet nozzle directs oil to the desired portion of the cylinder, rod & underside of piston.

• The crankcase features a tri-axis layout for the crank, main & drive axles.
– tri-axis design means lighter, more compact crankcases
– centralizes mass for excellent handling
• YZ450F inspired crankshaft & connecting rod features a carburizing process for excellent durability.
• Lightweight gear driven counter balancer shaft.
– reduces vibration for improved rider comfort & reduces rider fatigue
• 5-speed, wide ratio transmission utilizes a 2-bar, floating shift guide system & a 14 mm shift shaft.
– smooth, positive shifts
– good durability in the event of a crash (14 mm shift shaft)
– optimized ratios for good performance in difficult sections & solid top end speed for fast sections
– see spec page for gear ratios
• Heavy duty, multi-plate, clutch with quick access magnesium outer cover.
– clutch is designed for the rigours of enduro riding
– clutch action is light to reduce hand fatigue during extended races / rides
– quick access outer cover provides fast & easy clutch access
• 44mm Keihin throttle body fuel injection system.
– 10-hole injector with a 16 degree spray pattern
– maximizes fuel atomization for more complete combustion & excellent power delivery
– FI settings are specific to enduro racing / riding
– FI benefits include automatic adjustments to insure the optimum fuel – air ratio regardless of outside air temperature & altitude
– other benefits include excellent starting & excellent throttle response
– cold start knob also doubles as an idle adjuster
• The injector spray pattern, spray direction and the distance to the intake valves have been optimized. Forward mounted straight intake tract helps to maximize the benefits of the FI system & overall power output.
• Optional, compact, hand held “GYTR Power Tuner” allows tailoring of both fuel injection duration & ignition mapping.
– 9- different setting points can be accessed for both fuel duration & ignition maps
– maps can be stored & shared with other Power Tuners if desired
– easy access GYTR Power Tuner connector port
– NOTE: Competition Only Kit ECU is required for Power Tuner use on the WR450F

– front fork adjustments include: 20-way compression damping & 20-way rebound damping
– 25 mm front axle
– optional fork springs are available through Genuine Yamaha parts
• Fork features a twin-chamber, “Speed Sensitive System” design meaning the damper unit is in a separate structure (completely separated air & oil chambers) which prevents aerated fork oil from entering the inner damper assembly and degrading its damping abilities. Since the inner damper is pressurized, it also eliminates bubbles forming in the oil.
• Fork also features a Transfer Control Valve (TCV).
– TCV enhances damping from mid to full stroke & improves bottoming characteristics
– TCV offers more precise control throughout the full suspension stroke
– TCV is located on the upside of the spring & its function is controlled by piston speed, not piston position, hence the term “Speed Sensitive System fork”.
• Large “wrap-around” plastic fork protectors provide excellent lower fork tube protection.
– “self-supporting” design reduces friction for smoother fork operation.

– features separate adjusters for high- and low-speed compression damping
– shock is in-line with the center axis of the frame for excellent control
– shock valving & settings are tailored for enduro riding
– shock adjustments include: threaded spring preload, 20 -way low-speed compression damping, 2 turns of high speed compression damping & 30-way rebound damping
• 270mm floating front “wave-style” disc & compact twin piston Nissin caliper.
