Larger front & rear wheel
The YZ85 Large Wheel (LW) model raises the bar for off-road capability with a larger 48,26 cm front wheel and 40,64 cm rear wheel clad in high performance 70/100/19 front and 90/100/16 rear Dunlop® MX3S tyres. Perfect for the advanced 85cc rider looking for a more "big-bike" feel.
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.
Fully-adjustable suspension
Lightweight 36 mm 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.
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.
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.
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.
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 aluminium (vs. resin) impeller for maximum cooling efficiency.
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.
Fully-adjustable fork
The lightweight 36 mm KYB® inverted cartridge fork features 27,4 cm 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 30,48 cm of travel. The progressive linkage-type design improves bottoming resistance, allowing racers to charge harder and improve lap times.
Optimized chassis design
Built for demanding junior racers, the YZ85 LW's chassis is optimized for strength, rigidity and overall handling stability. The aluminium swing-arm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminium reduces weight.
Large-diameter brakes
Big wave-style brake discs offer improved self-cleaning and cooler-running performance. The 220 mm front disc and 190 mm 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.
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.
