New 2019 YZ85
The new 2019 YZ85 youth motocross bike arrives with major redesigns purely focused on performance. Featuring an all-new engine, suspension, and more.
All-New Engine
A newly-designed 85cc liquid-cooled 2-stroke engine featuring a case reed-valve intake and a mechanical Yamaha Power Valve System (YPVS) lies at the heart of the 2019 YZ85. Combined with a redesigned cylinder and head, crankcase, crankshaft, connecting rod, transmission, exhaust and CDI unit, this new YZ engine is claimed to provide broad, tractable power across the rev range without losing peak power at high RPM.

Updated Chassis and Optimized Ergonomics
The semi-double-cradle steel frame, removable subframe and redesigned aluminium swing-arm provide a nimble feel, confident handling and ease of maintenance. The ergonomics feature a flat, comfortable seat, four-position adjustable aluminium tapered handlebars and adjustable-reach levers to provide comfort and ease of movement for a wide range of young rider sizes.
Updated Brake System
For 2019, a new, stiffer front brake line with new routing improves braking feel, while 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.
Easily Tuned KYB® Coil Spring Suspension
The new YZ85 features KYB®’s race-proven, fully adjustable 36mm coil spring fork with one-piece outer tubes and tapered shape to provide optimal rigidity balance. This provides exceptional handling, bump absorption and ease of set-up for race-winning performance. The KYB® fully adjustable link-type shock utilizes specially designed damping characteristics to match the new chassis.
