yamaha YZ85

Back

The start of something special

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.

Some forty years on we're still a major force in youth MX - and it's this in-depth experience that gives the Yamaha the edge. Featuring advanced engine and chassis technology and all-new bodywork, the totally restyled YZ85 and YZ85LW large wheel look sharper than ever.

Its reliable 2-stroke, liquid-cooled, 85cc engine features revised port timing for even smoother and more useable power - and with its easy handling chassis and refreshed image, the latest YZ85 is the choice of future champions.
