Make no mistake; the YZ85 is every bit as serious a competition machine as its bigger-bore brethren.

From the knobs on its Dunlops, through the fully adjustable front and rear Kayaba suspenders, right through its ultra-rigid twin-spar high-tensile steel frame and clear into where the flat seat/tank junction meets the seat of your pants-the YZ85 means serious business.

You've got 85cc of high-revving liquid-cooled muscle multiplying through a six-speed gearbox , powering a package that weighs a mere 146 pounds.

The inverted Kayaba fork dishes out nearly 11 in. of supple, well-controlled wheel travel, you've got 11.1 in. out back. And, the light and powerful 220mm front and 190mm rear disc brakes provide controllable stopping power and feel.
