Introduction YZ85

Back in the day it was Yamaha who pioneered the first serious youth motocross bikes – and we’re proud of the fact that the YZ85 has launched the careers of so many top riders.

The YZ85/LW has a reliable 2-stroke liquid-cooled 85cc engine which produces smooth and useable power – and with its easy handling chassis and modern image, this cool Motocross bike is the choice of future champions.
