2008 Yamaha YZ85 (2-Stroke)

Every inch a competitor.

The 2008 Yamaha YZ85 may be the smallest member of the YZ family, but it’s a big time competitor. It has got power to burn with a liquid cooled, 85cc engine, 6 speed gearbox, and adjustable suspension up front and out back. This is one mighty mini.

The Yamaha YZ85 remains the mini of choice for young riders who are ready to get serious about motorcross.

With the same chassis and engine technology that goes into every 2-stroke YZ, the scaled-down YZ85 is a true competitor.

The YZ85, with its ultra-rigid high-tensile steel frame and 36mm inverted forks, weighs just 55kg (126lbs.) Powered by a compact but muscular liquid-cooled 85cc engine pumping the revs through a six-speed gearbox, this bike’s engineered to catch some major air — and trophies, too. Fully adjustable suspensions, front and rear disc brakes and almost 11″ of wheel travel highlight “for competition use only.” Truly, this is full-sized performance in a scaled-down package.

FEATURES:

Lightweight, compact, 84.7cc, liquid-cooled, crankcase reed-valve inducted, 2-stroke single.

Crankcase reed valve induction and 28mm Keihin flat-slide carburetor ensures seamless throttle response across the powerband. The aluminium carb body helps reduce weight.

Lightweight, forged piston means less reciprocal mass and less friction for a faster revving engine with great durability.

Digital CD ignition system provides a hot, precise spark and monitors engine speed to ensure optimal timing for quicker, stronger response during hard acceleration.

Smooth-shifting, 6-speed transmission with involute splines on main and drive shafts are mated to a heavy-duty, multi-plate clutch delivering maximum hook-up for outstanding acceleration and corner-exiting power.

Clutch cover features a quick remove sub-cover for fast, easy access during maintenance.

Lightweight radiator with large size cores and computer-designed louvers provides maximum cooling efficiency.

Washable, dual-stage, foam filter ensures great air filtering performance and easy, economical maintenance.

Lightweight exhaust system is specially designed to create a broad powerband with strong low-end punch. The aluminium silencer is re-packable to maintain optimum performance and reduced noise levels.

Rigid, semi-double cradle steel frame is ultra-lightweight and incredibly strong providing minimal flex for razor-sharp moto-wining handling

Detachable rear subframe allows easy access for suspension maintenance

Lightweight box-section aluminium swingarm provides excellent rigidity for awesome rear wheel control and traction.

Lightweight, adjustable 36mm inverted Kayaba cartridge fork provides 275mm (10.8″) of wheel travel and adjusts for compression and rebound damping. Adjustments include: 20 clicks of both compression and rebound damping. Their construction offers YZ125/250 type valving and low-friction seals to ensure a smooth, compliant stroke for superior suspension performance and handling. Optional fork springs are available through Yamaha Genuine Parts and Accessories.

Monocross link rear suspension features a fully adjustable Kayaba piggyback shock providing 282mm (11.1″) of wheel travel. The piggyback design helps to keep the shock cool during a long moto to provide fade resistant damping and consistent performance. Adjustments include spring preload, 20 clicks of compression and 20 clicks of rebound damping. Optional shock springs are available through Yamaha Genuine Parts and Accessories.

220mm front disc with twin piston caliper and stainless steel rotor deliver strong stopping power with excellent control and great feedback. “Shorty style” adjustable brake lever can be tailored to fit various hand sizes.

190mm stainless steel rear disc brake is squeezed by a single piston caliper. The caliper is protected by a rugged plastic protector.

Lightweight 17″ front and 14″ rear DID rims provide exceptional durability and help reduce unsprung weight for optimal suspension performance.

Premium Dunlop knobby tires enhance traction and cornering on a wide variety of tracks and terrain.

Slim line body design and flat seat provide excellent freedom of movement for the rider. The seat features a “gripper” type seat.

Sealed tapered steering head bearings for durability.

Cleated rear brake pedal and folding shift lever tip provide superb grip and excellent durability.

Wide, cast-alloy footpegs are serrated to provide superb comfort, grip and ground clearance.

Wide-diameter fuel tank cap and large tank opening ensures fast, hassle-free refuelling.

Stainless steel inner clutch cable ensures longer life and smooth operation

Sealed pivot on kickstarter helps reduce wear.

Rubber boots on clutch and brake levers help reduce dirt, mud, and water entry for improved durability.

Convenient lifting holes in side cover.

Rugged chain guide helps prevent chain from de-railing and also protects the rear sprocket.

Heavy-duty rubber swingarm protector.

Stylish crossbar pad.
