Product Details

3D MXR Chain by EK Chain®. Type: 520. EK ThreeD (3D) Premium motorcycle chain is Elegant, Strong, Detailed and Magnificent. It offers the ultimate shape with flexibility and strength. EK Chain set out to produce a premium chain that was as beautiful as it is strong. An impressive outer plate shape that offers a curved form to reduce weight and increase appeal is connected together with inner plates and pins that feature lightening holes to further reduce mass. QX2 X-Rings have a better wear-resistance and performance than standard QX-Rings by 30% resulting in a chain that puts 1% more power to the rear tire. 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.
