YZ85

With the same chassis and engine technology that goes into every YZ, the scaled-down YZ85 has something in common with you: it’s every inch a 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. Truly, this is full-sized performance in a scaled-down package.

Engine:

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, while aluminum 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 aluminum silencer is repackable to maintain optimum performance and reduced noise levels

Chassis/Suspension:

Semi-double cradle steel frame is ultra-lightweight and incredibly strong providing minimal flex for razor-sharp handling

Detachable rear subframe allows easy access for suspension maintenance

Lightweight, adjustable 36mm inverted Kayaba cartridge fork provide 275mm (10.8″) of wheel travel and adjust for compression and rebound damping. Adjustments include: 20 clicks of compression and 20 clicks of rebound damping. Their construction offers YZ250/125-design valving, low-friction outer tubes and internals to ensure a smooth, compliant stroke for superior handling and light steering

Monocross link rear suspension features a fully adjustable Kayaba piggyback shock providing 275mm (11.1″) of wheel travel. Adjustments include spring preload,20 clicks of compression and 20 clicks of rebound damping

220mm front disc with twin piston caliper and stainless steel rotor deliver strong stopping power with incomparable control and one-finger feel

190mm rear disc brakes features a stainless steel rotor and single piston caliper

Rugged, plastic rear caliper 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 variety of tracks and terrain

Features:

Slim line body design and flat seat and fuel tank provide excellent freedom of movement and weight transfer

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

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

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

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

Convenient lifting holes in side cover

Rugged chain guide helps prevent chain from de-railing
