This combination of the cylinder head and VHM 12° billet piston provides faster throttle response, torque and power. Our VHM high inertia crankshaft transfers the high engine power output smoothly to the rear wheel, without being too aggressive. It will ensure better handling and riding for the young riders!
This upgrade kit contains our 12° VHM piston, which can only be used in combination with our special insert for 12° piston.
