YZ450F
With more World Championships this decade than any other manufacturer, Yamaha is the dominant force in motocross. And even before the gate drops, the latest YZ450F is built to strike fear
into the hearts of the opposition.
Now equipped with an even more agile-handling chassis and revised suspension settings, the 2009 YZ450F is designed to keep you way out front!
Running with a new ultra-light swingarm, as well as a lighter rear hub and stiffer rear axle, the 09 bikes reduced unsprung weight and revised rigidity balance means you can turn quicker
and exit bends faster than ever before.
2009 YZ450F. Keep on winning.
