RK ZXW 530 x 120 Black Scale XW Ring Superbike Motorcycle Racing Drive Chain

RK chain is the top choice in drive chains in terms of quality and durability

With the addition of Black Scale coatings, they are now killers in terms of looks too

Black electroplated outer links, gold inner links and gold rivet heads are combined with RKs patented sealing rings

RK sealing rings are made from a Nitrile Butadiene composite with a refined "X" shape

This means the seal has TWO lubrication pools and contact lips vs the single contact design of an O ring seal

It helps protect against high speed abrasion, heat build up, torsional flex and any loss of sealing lubricant

This chain gives up to SEVEN times longer wearlife compared to RK standard chains

XW-Ring chains are ideal for high-speed, high-horsepower performance applications
