Chain DID ZLV Super Heavy Duty X-Ring Black - Suzuki RF 900 RX 1999

DID 532 ZLV X-Ring Chain

DID's ZLV Chain uses patented X-ring seals. Like O-rings, X-rings function to seal in lubrication and keep dirt out.

Where the cross section of an O-ring is circular, the cross-section of an X-ring is X or cross-shaped. This gives the seal additional contact points compared to the O ring, offering superior sealing and protection against dirt and grit getting stuck under the seal.
In addition, when under pressure, an O-ring becomes squashed and causes friction. An X-ring, when under pressure, diverts this pressure by twisting instead, so an X-ring decreases friction between side plates and reduces power loss by 50% of any other type O-ring chain.

DID's X-rings have 40% greater wear resistance than an O-ring chain and 33 times that of a DID standard chain. This means more resistance to stretching, bowing and warping, and smoother handling. With proper maintenance, an X-ring chain will last longer than any O-ring or unsealed chain.

Sealed chains require lubrication every 500km (300 miles) in order to prevent surface rust and ensure performance.
