Slim rider interface
Bodywork components and seat designed to offer a slim, natural riding position making it easier for racers to go fast. Slimmer shroud design contributes to improved ergonomics.
Rear shock absorber
Revised shock damping settings result in a reduced "kicking" tendency, facilitating corner entry. Dual compression adjustability offers a wide range of tuning options. Kashima Coat on the tank cylinder improves action.
249 cm3 liquid-cooled, 4-stroke Single
Tuned for high performance, the wide powerband extends way into the over-rev. Factory-inspired refinements contribute to increased performance. Used for the first time in a mass-production machine, a new high-performance piston with bridged-box bottom features the same design as our factory racers. Additional modifications offer enhanced durability and reliability.
Radiators
New thicker, wider radiators with more widely spaced cores/fins are stronger, offer better resistanceto mud build-up while maintaining cooling performance. Also lighter overall, with reinforcing brackets unnecessary.
Renthal handlebar
Factory-style handlebar and pad saves weight.
All-aluminium perimeter frame
Slim aluminium perimeter frame is a lightweight construction composed of forged, extruded and cast parts.
New Uni-Trak rear suspension
Linkage mounts below the swingarm for more precise suspension tuning. Revised linkage ratios contribute to increased rear wheel traction.
Petal brake discs
Front and rear petal brake discs offer efficient braking performance.
Showa twin-chamber fork with titanium coating
Low-friction titanium coating (a class first) smoothes fork action. Revised settings result in a less forward-leaning posture. New damping settings and a revised steering stem offer improved action and increased absorption performance. Kashima Coat further reduces friction.
