YZ85 / YZ85LW
The 2023 YZ85/LW continues to offer the proven liquid‑cooled YPVS‑equipped 85cc powerplant, fully adjustable suspension and large diameter brakes that were fitted to the 2022 model to expand overall performance.
Rider ergonomics are top shelf thanks to a narrow tank design, flat seat and slim, symmetrical radiator shrouds. This enables great freedom of movement for smooth shifting of body weight and supreme machine control.
Along with the bodywork, a sharp premium graphics scheme inspired by its YZ125 sibling highlights its distinctive race bred YZ DNA. The seat and rear bodywork also enable the rearpositioned straight‑through intake for strong power in the low rpm range.
For demanding junior racers, the YZ85 features a strong main frame, swingarm and rear wheel axle. The aluminium swingarm strikes a balance between longitudinal and torsional rigidity for great handling stability.
A removable rear subframe constructed from lightweight, high strength aluminium reduces weight. The rear brake master cylinder has a built in sub reservoir providing linear brake response and high levels of control.
The YZ85LW (Large Wheel) model takes the race‑winning YZ85 formula and enhances offroad capability even more with the addition of a larger 19‑inch front wheel and 16 inch rear wheel wrapped in high performance Dunlop MX3S tyres.
A long swingarm accommodates the large rear wheel for handling stability. The YZ85LW is designed to be the ideal transition between the standard YZ85 and the full size YZ125, perfect for those advanced 85cc riders looking for a big bike feel.
