THE HIGH-SPEED PURSUIT OF PERFECTION

Last season, the new 2008 YZ450F jumped right in by winning the AMA Motocross Championship, then backed it up with the 2008 Supercross title. We decided to not fix what wasn't broken, but that doesn't mean we didn't make a few changes to our flagship YZ. For 2009, the best-handling big-bore you can buy corners even sweeter, and looks even more radical.
