DID’s 520 ZVM-X is a premium X-Ring sealed drive chain engineered for high-torque, high-horsepower motorcycles. Its X-Ring design improves sealing while reducing friction for efficient power transfer and long service life.
The DID 520 ZVM-X Chain is built for riders who demand maximum durability and consistent performance from their final drive. Designed for heavyweight, high-torque motorcycles, this X-Ring sealed chain delivers strong power transfer while helping reduce friction and power loss compared to conventional sealing designs.
Its patented X-Ring® seal uses a twisting action to improve sealing performance, helping keep lubrication where it belongs and contaminants out. Combined with DID’s Direct Energy Transfer technology (inspired by MotoGP development), the ZVM-X series is engineered to resist stretch under load—a key benefit for powerful street bikes and adventure bikes that put sustained stress into the drivetrain.
