RK’s ZXW series is used for both racing and general use. 

ZXW chains feature MotoGP and FIM Suzuka 8 Hour Endurance technology and has proven superiority by winning 35 first place finishes out of 39 races at the FIM Suzuki 8 Hour Endurance Race. Several features are required for an exceptionally performing endurance race chain. These include:

• Low Friction – The chain must not reduce power output from the engine
• High Tensile Strength – The chain must be able to withstand the extreme loads of race engines
• Consistency – The chain must consistently perform during the entire race duration
• Fuel Efficient – The chain must not decrease the engine’s fuel efficiency

All these features are in perfect balance in the construction of the ZXW chain. RK’s ZXW series chains are ideal for high-speed, high-horsepower performance applications.

RK’s XW-Ring seals provide three contact lips and two lubrication pools to protect against dirt and debris, high-speed abrasion, heat buildup and the loss of lubricant under extreme conditions.
