New cylinder head
Piston crowns changed to suit revised combustion chambers
Larger valves (Intake up by 0.5mm)
More aggressive camshafts
Valve springs are new while retainers have been changed to lightweight sintered aluminium
New twin injector fuel system (Secondary injector in the airbox)
New breathing passageways in cylinder to improve crankcase breathing and reduce losses
Closer ratio gearbox (similar to race kit item)
New fork settings (New damping rates and internals)
New diamond-like-carbon coating on fork inner tubes
Rear suspensions lower spring holder is electrostatically coated to prevent corrosion
Matt black frame and swingarm
Green drive chain
Redesigned airbox with a removable duct (when duct is removed more power results)
