YZ85
Back in the day it was Yamaha who pioneered the first serious youth motocross bikes – machines that launched the careers of many top riders.
Some forty years on we’re still a major force in youth MX - and it’s this experience that gives Yamaha the edge. Featuring advanced engine and chassis technology and sharp bodywork, the YZ85 is still kicking butt and taking names.
A reliable 2-stroke liquid-cooled 85cc engine produces smooth and useable power – and with its easy handling chassis and AUS factory fitted race kit, this is the choice of champions.
