Yamaha YZ description
2014 YAMAHA YZ85, Key Features:
Liquid-cooled, 85cc 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.
Owning a Yamaha 2-stroke is less expensive to maintain.
Engine:
85cc 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.
