Yamaha YZ85 Team Yamaha Blue
YPVS 2-STROKE ENGINE
The 85cc liquid cooled engine features the Yamaha Power Valve System (YPVS) that boosts overall performance and contributes towards the bike's easy to use torque. Running with a high compression ratio - and equipped with a close ratio 6-speed transmission - the YZ85 delivers outstanding acceleration with race winning power.
LIGHTWEIGHT CHASSIS DESIGN
Built for demanding junior racers, the YZ85's chassis is optimised for strength, rigidity and overall handling stability. The aluminium swingarm offers refined balance between longitudinal and torsional rigidity, and the removable rear subframe constructed from lightweight, high-strength aluminium reduces weight.
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.
FULLY ADJUSTABLE FRONT FORKS
The lightweight 36mm KYB® inverted cartridge fork features 275mm 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.
ADVANCED INTAKE DESIGN
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.
WAVE-STYLE BRAKE DISCS
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.
