VICTORY…NEVER GIVEN, ALWAYS EARNED.

2019 Yamaha YZ85: 

Lightweight. Reliable. Born to perform. Step up, then step up to the podium. Victory awaits.

Step up to the perfect bike and continue the journey of earning victory after victory. The YZ85 has all the lightweight, 2‑stroke reliability and agility you’ve come to expect from Yamaha.

Redesigned from the ground up, the new YZ85 has been built to dominate the 85 cc class. Featuring a new engine with the Yamaha Power Valve System (YPVS), new suspension, revised six-speed transmission and adjustable ergonomics, the 2019 YZ85 is ready to win races straight off the dealership floor.

ENGINE
For 2019, the YZ85’s compact, lightweight 85 cc two-stroke engine features revisions to the intake, exhaust and transmission. The addition of YPVS creates broad, tractable power across the rev range without losing peak power at high rpm.

CHASSIS
A new front fork, new swingarm, new wave-style brake rotors and adjustable ergonomics complement the YZ85’s semi-double-cradle, single-backbone steel frame and fully adjustable suspension.
