This chain kit is designed for street and racing motorcycles over 1000 cc with high torque and power, or where maximum strength and chain lifespan are required. The kit consists of carefully matched components from leading global manufacturers.

Chain D.I.D. ZVM-X

The D.I.D ZVM-X Series utilizes our patented X-Ring seal and has greater strength than the VX Series and is designed for heavyweight motorcycles with tremendous torque and horsepower. The twisting action of the X-Ring® increases its sealing performance and its four contact points minimizes power loss. The ZVM-X Series’ Direct Energy Transfer, born from our experience in MotoGP, means greater stretch resistance under load.
The ZVM-X chain is a great chain for high powered street bikes but may also be utilized on adventure bikes.
**ZVM-X and ZVM-X2 CONNECTING LINKS AREN'T INTERCHANGABLE** (Varying pin lengths)

Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

JT Steel Front Sprockets

JT Steel Front Sprockets are manufactured using only the finest grade of SCM420 chromoly steel alloy. The JT Steel Sprockets range now contains over 2,500 parts for all motorcycles and ATVs.
