Several changes to the 2009--straight from Rider magazine, 9/08:
1. '09 meets CA emission standards (biggest change).
2. Less suspension travel, and slighter shorter seat height.
3. Thicker wheel spokes, and more street oriented stock tires (Dunlop D605).
4. Improved rear brake--240mm petal rotor (formerly 220mm).
5. Tweaks to carb and radiators.
A serious side effect of life is death. Ride while you can.
