2023 Yamaha YZ85

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

Features may include:

• 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 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.

• 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.

• 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.

• Optimized Chassis Design

Built for demanding junior racers, the YZ85s 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.

• 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.
