RK Chain Links
RK currently has FIVE types of sealed-ring chains. Each has its own features and benefits.
- O ring and RX Rings came first. Each a great product in their own right and broadly similar to the competition's current offerings.
- After several years of development, RK added the XW range of sealed chains to radically improve chain life and performance.
- As racing expanded into several different genres, RK also added the ultra thin U-Ring and UW-Ring sealed chains.
- Each seal type is specifically designed for a particular use to provide the ultimate in rotating efficiency with minimum friction, while providing a longer chain life.
- Do not compromise: Maximise the motorcycle's performance by fitting RK chain. Mark Marquez does and he does pretty well...
EXW is specifically designed for ATV/Off-Road vehicles and is the best high-speed, extreme heat, off-road performance chain available. EXW chains feature XW-Ring seals to better survive the abrasive conditions that exist in hostile off-road conditions.
