The 4-stroke bell rotor has been manufactured by Huasgheng 142F chain-drive transmissions and flying horse 5G. The installation process is simple and quick, as you only have to loosen the bell from the rotor for making a new installation. Do not at any cost torque the bell rotor as it may damage it. The rotor has a chain-driven transmission. The bike spare part is not compatible with the Grubee 4G transmission, gear, and belt-driven transmissions. 

It weighs approximately 226.8 frames or 227 grams. 

Do you have a working engine, but you cannot take your anywhere along, then your bell rotor is probably in a bad state.
