Chassis / Suspension
- FULLY-ADJUSTABLE FORK: The lightweight 36mm KYB® inverted cartridge fork features 10.8 inches of travel with compression and rebound damping adjustability. Complete with low-friction outer tubes and internals, the damping settings offer enhanced performance across a range of conditions and rider abilities.
- FULLY-ADJUSTABLE SHOCK: Rear suspension features fully adjustable KYB® link-type shock with race-tested valving and 11.1 inches of travel. The progressive linkage-type design improves bottoming resistance, allowing racers to charge harder and improve lap times.
- HIGH PERFORMANCE TIRES: Dunlop® MX3S tires provide exceptional traction on a variety of tracks and terrain.
- LARGE-DIAMETER BRAKES: Big wave-style brake discs offer improved self-cleaning and cooler-running performance. The 220mm front disc and 190mm rear disc deliver strong, precise stopping power. Rear brake master cylinder also includes built-in sub-reservoir to provide more linear brake response and increased control.
- LIGHTWEIGHT WHEELS: Lightweight 19-inch front and 16-inch rear rims are durable and reduce unsprung weight for optimal suspension performance.
- OPTIMIZED CHASSIS DESIGN: Built for demanding junior racers, the YZ85 LW's chassis is optimized for strength, rigidity and overall handling stability. The aluminum swingarm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminum reduces weight.
Engine
- ADVANCED INTAKE DESIGN & HIGH-FLOW AIRBOX: Advanced intake design allows for a straighter, more efficient draw of air into the intake tract. High-flow airbox ensures excellent air filter performance and easy maintenance.
- DURABLE TRANSMISSION: The transmission features oversized gears to provide enhanced engagement and smoother shifts.
- HIGH CAPACITY RADIATOR: Lightweight radiator has large cores and louvers. Water pump features a cast aluminum (vs. resin) impeller for maximum cooling efficiency.
- POTENT YPVS™ TWO-STROKE ENGINE: The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System (YPVS™) for broad power across the rev range without losing peak power at high rpms, reducing the need for frequent shifting.
- TUNED CRANKCASE & INTAKE: The crankcase design features a spacer-style reed valve intake for improved air/fuel flow, which inhales through a 28mm Hitachi Astemo® Keihin flat-slide carburetor for seamless throttle response.
- TUNED EXPANSION CHAMBER: Carefully matched to suit the YPVS™-equipped engine, the exhaust expansion chamber optimizes gas flow for enhanced power delivery, especially in the low- and mid-range.
Other Features
- ADJUSTABLE RIDER ERGONOMICS: The four-position adjustable handlebar mounts and taper-style handlebar allow the rider to tune the handlebar position to suit their size and preferences. Flat seat and narrow fuel tank design, along with smoothly integrated body panels and slim shroud width, combine to enable greater freedom of movement for increased control and confidence.
Top Features
- FULLY-ADJUSTABLE SUSPENSION: Lightweight 36mm KYB® inverted cartridge fork features low-friction outer tubes, external compression and rebound damping adjustability, paired with a race-proven fully-adjustable KYB® rear shock. Both offer loads of suspension travel to tackle serious off-road competition.
- HIGH-QUALITY EMBEDDED GRAPHICS: Inspired by its YZ125 sibling, the aggressive graphics scheme highlights the YZ's unmatched racing pedigree. Premium Yamaha Blue and dark blue graphics are embedded to provide excellent durability and scratch resistance.
- HIGH-SPEC WHEELS & BRAKES: Stylish blue, lightweight 19-inch front and 16-inch rear rims are durable, reduce unsprung weight for optimal suspension performance, and come wrapped in Dunlop® MX3S tires for exceptional traction. Big 220mm and 190mm disc brakes offer precise control and outstanding stopping power.
- LARGER FRONT & REAR WHEEL: The YZ85 Large Wheel (LW) model raises the bar for off-road capability with a larger 19-inch front wheel and 16-inch rear wheel clad in high performance 70/100/19 front and 90/100/16 rear Dunlop® MX3S tires. Perfect for the advanced 85cc rider looking for a more "big-bike" feel.
- OPTIMIZED CHASSIS DESIGN: Built for demanding junior racers, the YZ85 LW's chassis is optimized for strength, rigidity and overall handling stability. The aluminum swingarm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminum reduces weight.
- PERFORMANCE-MINDED ERGONOMICS: The flat seat and narrow fuel tank design, along with smoothly integrated body panels and slim shroud width, combine to enable greater freedom of movement forward and back, allowing the rider to easily shift body weight for increased control and confidence.
- YPVS™ TWO-STROKE POWER: The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System (YPVS™) for increased low- and mid-range power without losing peak power at high rpms, reducing the need for frequent shifting.
