Yamaha's profilation of this bike 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.
