Based on the MXGP World Championship winning YZ450F, the WR450F employs Yamaha’s innovative reverse cylinder head and rearwards slanting cylinder. Having convincingly demonstrated its winning performance at the highest level, this industry-leading engine design offers high levels of controllable and linear torque, while this design’s greater mass centralisation contributes towards the bike’s agile handling character.
Together with the compact and light-handling YZ-F based chassis, the WR450F delivers major improvements in terms of weight, power characteristic, agility and rideability.
The YZ450FX is a cutting edge weapon specially honed for the bush. It shares the revolutionary rearward-slanted cylinder design of our YZF/WR range and delivers a controllable, torquey power character with strong top-end power tuned specifically for enduro racing.
A YZ450F Bilateral Beam aluminium frame combines with industry-leading, KYB twin chamber suspension to provide a shorter wheelbase and quicker steering experience to get through the trees – fast.
This model sports a powerful 270mm front brake for outstanding machine control, a model specific clutch system and new switch-free electric start.
All this plus an 18-inch rear wheel and XC racing tyres means the YZ450FX is ready to win straight from the crate.
Featuring an innovative reverse cylinder head engine, the ground breaking Yamaha WR250F has demonstrated it can outperform the toughest opposition.
With DNA lifted straight out of the championship winning YZ250F, the WR250F benefits from a range of important technical changes – such as an all-new reverse cylinder head and revised chassis and suspension – that are aimed at delivering increased performance and enhanced rideability.
This purpose built enduro racer is built for riding in the bush – fast.
Developed as a sister machine to the YZ250X two-stroke, this cross country racer is equipped with a shorty muffler and slightly firmer suspension settings than WR250F. And with no lights, speedo, bashplate or a radiator fan, the FX tips the scales at 4kg lighter than the road registrable WR250F.
Like YZ250X, the YZ250FX is available in two versions – standard and with a recreational registration lighting kit (R model) that includes an aluminium bashplate, handguards, rearview mirror, lights and a horn. This allows the model to qualify for recreational registration in applicable states.
Two-stroke version of YZ250FX gives an instant hit of two-stroke power in a lightweight enduro specific package.
Riders who like the easy maintenance, sharp handling and incredible power delivery of the YZ250 can now access this in the bush. A revised engine and a wide ratio gearbox have harnessed the power while an 18in rear wheel with off road tyres, a sidestand and reserve fuel tap add the creature comforts. We’ve even slimmed down the expansion chamber to avoid clipping trail obstacles. And that class leading KYB twin chamber suspension is especially tuned for enduro riding.
Also available with optional recreational rego lighting kit (R model).
