2018 Yamaha YZ65


Featuring an all-new engine, chassis, suspension, bodywork and more, the 2018 Yamaha YZ65 is designed to provide young riders with top-notch performance and reliability on the way to the victorYZone.

Features may include:

The YZ65's liquid-cooled, two-stroke, single-cylinder engine features the Yamaha Power Valve System (YPVS), providing excellent power and torque characteristics. Based on the YZ85, the YZ65's engine has been thoroughly revised with a host of new components: piston and rings, exhaust pipe, intake manifold, reed valve, connecting rod and much more. The engine is mated to a 6-speed transmission with optimized gear ratios.


The all-new YZ65 draws upon Yamaha's decades of leading track performance and proven durability. Adjustable front and rear suspension, a tapered handlebar and YZ450F-inspired bodywork are just a few of the trickle-down highlights of the newest YZ model.
