TOP FEATURES |
CHAMPION’S CHASSIS
BALANCE MEETS PRECISION
A new lightweight perimeter frame, revised swingarm, and longer wheelbase offer improved rear-end traction, controllability, and stability. Optimized rigidity balance makes for a steady front-end feel that translates to precise cornering performance.
CHAMPION’S CHASSIS
RACE-READY
A high-performance 49mm inverted Showa coil-spring fork handles suspension duties up front, with optimized suspension settings for improved shock absorption. The fork's internal valving, adjusters, and oil level are finely tuned, and the large-diameter inner tubes (the same size as on our factory motocross racers) enable the use of large damping pistons for smooth action and firm damping.
CHAMPION’S CHASSIS
CHAMPIONSHIP-PROVEN
An updated New Uni-Trak® rear suspension system features a Showa shock with adjustable dual-range (high- and low-speed) compression damping, adjustable rebound damping, and adjustable preload. The result is optimal damping and rear-wheel traction.
CHAMPION’S CHASSIS
FREEDOM TO FLOW
A new, improved seat and slim shrouds enhance appearance and ergonomics.
CHAMPION’S CHASSIS
ADVANCED STOPPING POWER
A high-performance front and rear Brembo brake package delivers strong, consistent stopping power. Up front, a Brembo brake caliper and master cylinder are complemented by a steel-braided brake line that sharpens feel and controllability, while new rear Brembo brake components help smooth out corner entry for quicker cornering.
