YZ85LW - First choice for future champions
We’ve lost count of how many of today’s top riders started out on a Yamaha YZ85. And when you take a look at how much technology this thoroughbred offers, it’s easy to see why it’s the leading choice for future champions. Driven by a liquid-cooled two-stroke engine housed in a lightweight chassis, this junior motocross bike is a scaled down version of our adult YZs. And the race-bred long-travel suspension systems are designed to master the most extreme tracks. Available in standard and large wheel (LW) versions, the YZ85/LW is the place where tomorrow’s champions are starting out.
