Victory. Never given, always earned

The YZ85 is a legend in the youth motocross scene. It’s the bike that inspired many of today’s top professional racers and helped them on their path to MX glory. And with its punchy performance, the YZ85 is the dirt bike that can turn young riders’ dreams into reality.

The 85cc liquid-cooled 2-stroke engine comes with a Yamaha Power Valve System (YPVS) that delivers a wide spread of explosive power – giving genuine advantage over the competition.

And with fully adjustable forks, wave-type front and rear discs and adaptable ergonomics, the YZ85 has the technology to launch riders all the way to the top. Plus its sharp styling and factory-inspired graphics show the world you’re serious about winning.
