Notes
  • New cylinder head for 09 with different porting & valve seats.
  • Rear spring losses free height quickly.
  • 23.5mm offset triple clamps for 2009. Best results are with 22mm offset clamps.
  • Rear spring rate selection & sag heights are crucial, 100mm sag must be kept.
  • Rear shock stock setting does not have enough rebound dampening for many riders, same setting as 2008.
  • Needs a pipe.
  • Stock 12 tooth front sprocket wears chain guides.
  • 42 Pilot can be used at altitude.
  • Convert engine to wet sump if clutch life is short.
  • Needs a pipe.
  • 20mm offset is standard on the 2 way adjustable clamps.
  • Fork & shock settings are too stiff for most riders, hence the clicker settings.
