Victory: Never Given, Always Earned



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

Top Features

• YPVS™ Two-Stroke Power: The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System for increased low- and mid-range power without losing peak power at high rpms—improving rideability and 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.
• High-Spec Wheels and Brakes: Stylish blue, lightweight 17-inch front and 14-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 one-finger stopping power.

Engine Features

• Potent YPVS™ Two-Stroke Engine: The 85cc liquid-cooled, two-stroke engine features the Yamaha Power Valve System for broad power across the rev range without losing peak power at high rpms—improving rideability and reducing the need for frequent shifting.
• Tuned Crankcase and 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. Threaded portion of the clutch shaft diameter has also increased from 12mm to 14mm.
• High Capacity Radiator: Lightweight radiator has large cores and louvers. Water pump features a cast aluminum (vs. resin) impeller for maximum cooling efficiency.
• High-Flow Airbox: Airbox design ensures excellent air filter performance and easy maintenance.
