YAMAHA YZ 250

Yamaha's profilation of this bike

Bred For Battle We built the first production YZ250 in 1975. It commenced kicking tail immediately and promptly set the standard by which competition bikes were measured. Even after all the victories and championships since then, including more AMA Supercross wins this season than anybody else (per Chad Reed), our beloved Supercross contender continues its relentless march toward perfection.
