Yamaha has just released its 2009 range of competition off-roaders, including a much-upgraded YZ450F(pictured) and YZ250F.
Both machines have had some major work down to the chassis, including new swingarm, redesigned rear hub with larger diameter axle, and new suspension settings at both ends.
The bikes also now run a four-position adjustment for the handlebar.
Prices are $11,499 for the 450 and $9299 for the 250.
