2009 YZ85 motorcycle

Key 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.

 Engine:

    * 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.

 Chassis/Suspension:

    * Rear subframe is removable to allow easy maintenance.
    * Lightweight 36mm KYB? inverted cartridge fork features 10.8 inches of travel with compression and rebound damping adjustability, and low-friction outer tubes and internals.
    * Rear suspension features fully adjustable Kayaba link-type shock 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.
    * Dunlop? knobbies provide great traction on a variety of tracks and terrain.

 Additional Features:

    * Wide handlebar and flat fuel tank, radiator shrouds, side panels and rear fender provide rider with leverage and freedom of movement and weight transfer.
    * Wide footpegs provide superb comfort, grip and ground clearance.
    * Separate clutch cover with transmission oil filler opening makes for easy maintenance.
    * Fuel tank cap is wider-diameter for easier usage, and large tank opening ensures fast, hassle-free refueling.
