There are many chain manufacturers in the motorcycle industry but most (including some Japanese manufacturers) only offer a single type of sealing ring, using a "one type fits all approach" which is used on all their drive chains.

This can be inefficient depending on the intended use. .

Different types of seals for different applications maximises efficiency and performance

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...
  • RK KRO O-ring chain is manufactured using high precision assembly technology and are optimized for maximum grease sealing while exercising friction control.
  • KRO O rings are made from an advanced Nitrile Butadiene composite for maximum performance and wearlife.
  • Heat treated hi-carbon alloy steel with seamless rollers and shouldered bushings.
