520GP X 3D Chain - 520GP3D120GXG

3D parts are precisely manufactured, leading to a greater improvement of transmission efficiency, better acceleration and efficient engine work. Features an original special plate with a lightening hole. EK creates a hole on both ends of a pin to lighten the chain without weakening the plate according to computer analysis. The edge-cut inner plate reduces friction and realizes smooth engagement with sprocket. This plate enables the chain to be light, removes mud from the hole and dissipates heat effectively.
