Product Detail

Fits all Lifan 50-120cc with 14mm x 17mm shaft + 140cc engines with 17mm shafts plus many older Honda engines like the CT 70 and Z50. All of Hooper Imports loose engines are shipped with a factory supplied 14 tooth sprocket. By changing this sprocket with a larger one you will increase top end speed and decrease torque proportionately.

Stock Lifan’s use a #420 chain for engines between 50 and 110cc plus 140cc. Their 125cc engine uses a #428 chain and has a different mounting spline than the other engines. The 120cc engine uses the #420 chain in most cases and has the same mounting splines as the 50-110cc and 140cc engines. You must purchase the correct sprocket for your engine type and chain. You may need to add or subtract length to your chain when changing sprocket sizes.
