FEATURES
- Liquid-cooled, 84.7cc crankcase reed-valve-inducted six-speed is
light, compact and designed to deliver hard-hitting, moto-winning power throughout the rpm
range.
- Ultra-rigid, single-backbone, semi-double-cradle frame is
lightweight and strong for sharp handling.
- Fully adjustable suspension allows a broad adjustment range to suit
everybody from rank novice to mini expert.
|
- 84.7cc liquid-cooled, crankcase reed-valve-inducted, two-stroke
engine inhales through a 28mm Keihin® flat-slide carburetor; seamless throttle response
across the powerband is the result.
- Digital CDI ignition system puts out a more precise spark and
monitors engine speed to ensure optimal timing for quicker, stronger response during hard
acceleration.
- Smooth-shifting, six-speed close-ratio transmission with heavy-duty,
multiplate clutch delivers maximum hookup for outstanding acceleration and corner-exiting
power.
- Involute spline set-up in clutch means smoother shifting under power
with great durability at competition-level usage.
- Two-piece clutch cover provides easy access during maintenance.
- Lightweight radiator has large cores and louvers, and the water pump
features a cast aluminum (vs. resin) impeller for maximum cooling efficiency.
- Lightweight exhaust system design helps create a broader powerband
with stronger low-end punch.
- Airbox design ensures greater air cleaning performance and easier
maintenance.

of travel with compression and rebound damping adjustability, and low-friction outer tubes
and internals.

with 11.1 inches of travel and race-tested compression damping valving.
- 220mm front disc and 190mm rear disc brakes with stainless steel
rotors deliver strong, precise stopping power.
- Lightweight 17-inch front and 14-inch rear rims are durable and
reduce unsprung weight for optimal suspension performance.

terrain.

rear fender provide rider with leverage and freedom of movement and weight transfer.
