– 2006 Yamaha YZ85


With the same chassis and engine technology that goes into every YZ, the scaled-down YZ85 has something in common with you: it’s every inch a competitor.

The YZ85, with its ultra-rigid high-tensile steel frame and 36mm inverted forks, weighs just 55kg (126lbs.) Powered by a compact but muscular liquid-cooled 85cc engine pumping the revs through a six-speed gearbox, this bike’s engineered to catch some major air — and trophies, too. Truly, this is full-sized performance in a scaled-down package.
