Yamaha revealed two new 250cc off-road race bikes in the WR250F enduro and YZ250FX closed-course racer.
The two machines share the same basic DNA, featuring the same 249cc rearwardly-slanted single-cylinder engine and a similar bilateral beam frame from the YZ250F motocrosser. Yamaha added a sixth gear for the new models as well as electric start and swapped out the YZ250F’s 19-inch wheel for 18-inchers.
The YZ250FX is tuned more for cross country or hare scramble competition, with specifically tuned fuel mapping and cross country optimized clutch plate, springs, push lever and oil valve. The KYB air/oil separation Speed Sensitive System fork and rear shock are specifically tuned for the rigors of cross country racing. The FX also comes equipped with Dunlop AT81 tires designed specifically for cross country racing.
Other features for the FX include quick-adjust clutch, quick-release quarter-turn Dzus air box fasteners and a 2.1-gallon fuel tank. The YZ250FX also comes pre-wired for an optional radiator fan.
The WR250F shares many of the same characteristics as the FX but is tuned more for enduro competition. Yamaha added a headlight, taillight, skid plate electric radiator fan and onboard enduro computer offering speedometer, odometer, average speed, clock and other information. The suspension and fuel injection are tuned for enduro riding, while the wheels are wrapped in enduro-spec rubbers. The WR250F is also 50-state compliant for off-road use.
The 2015 Yamaha YZ250FX is priced at $7,890 while the WR250F costs a bit more at $7,990. Both models will be offered in Team Yamaha Blue and White and are expected in showrooms in November.
