POWER & PERFORMANCE

- Keep It Light — Experience increased engine performance and lighter weight with a Pro Circuit titanium race exhaust system*.
- Light Pull & Self-Adjusting — A coned disc-spring hydraulic clutch offers light clutch pull and a wide engagement range.
RACE-READY SUSPENSION
- Race Ready — Experience unmatched suspension performance with the highly adjustable ø49 mm Showa Coil Spring Front Fork.
- Gain Traction — The adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload come thanks to the New Uni-Trak rear suspension system, featuring a Showa shock with Kashima Coating outer tube.
- Perfect Fit — The XTRIG ROCS-TECH (Revolutionary Opposed Clamping System) clamps the upper fork tubes from opposite directions helping to reduce inner tube distortion and allowing the fork to flex naturally.
