Victory Never Given, Always Earned

Built for fun. Built to win. The renowned YZ85 serves up big bike specs in a small bike package.

Features

Potent YPVS Two-Stroke Engine

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.

Optimized Chassis Design

Built for demanding junior racers, the YZ85'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.

Fully-Adjustable KYB Suspension

Lightweight 36mm KYB inverted cartridge fork features low-friction outer tubes and internals along with compression and rebound damping adjustability. It's paired with a race-proven fully-adjustable KYB rear shock with a progressive linkage-type design for improved bottoming resistance. Both offer loads of suspension travel to tackle serious off-road competition.

Large-Diameter Wave-Style Disc 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.

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 for increased control and confidence. Additionally, a four-position adjustable handlebars allow riders to tune the bar position to suit their size and preferences.
