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.
After several years of development, RK added the XW range of sealed chains to radically improve chain life and performance.
This means less time replacing the chain and more riding with a chain you can trust.
Do not compromise: Maximise the motorcycle's performance by fitting RK chain. Mark Marquez does and he does pretty well...

- OEM for all major Japanese manufacturers
- RK's RX-Ring technolohy
- Twice the wear life of a standard 530 chain
- High tensile strength
- Light weight
- Low Maintenance
- Less torsional friction
RK is the leading manufacturer of OEM motorcycle drive chain to all major Japanese manufactures. With over 40 years of supply to the largest manufactures including Honda, Suzuki, Yamaha, Kawasaki and Triumph, RK has years of experience which it utilises to ensure every chain it produces exceeds all expectations. RK also remains the first choice for many race teams from Moto GP, Motocross and Rally, it's superior quality gives their competitors the edge. Maximise your motorcycle's performance by fitting RK chain. Mark Marquez does and he does pretty well...
The 530 XSO features RK's standard X-Ring technology, the RX-Ring. The special shape of the X-Ring allows for 4 points of contact between the ring and chain with a lubricant reservoir in the middle. This allows the 530 XSO to have the twice the wear life of a standard 530 chain whilst requiring less maintenance. The 530 XSO is designed to combine rigid strength with a low weight providing the feeling of light acceleration without compromising on wear resistance. Affordable, long lasting performance RX sealed chain. The XSO series offers less torsional friction and increased 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...
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.

RK’s NEW MXZ5 Supercross Racing chains are made for the serious supercross and motocross racer. MXZ5 chains feature chromoly steel construction with seamless rollers and bushing.
RK’s reinforced chromized pins drastically improve the wear resistance more than two times compared to normal non-sealed chains while absorbing shock loads from extreme jumps.
All components are heat treated using RK’s exclusive HIT (Heat Induction Transfer) process.
520MXZ5 has a maximum tensile strength rated at 8,600 lbs and is suitable for professional level 125cc to 500cc class racing.
MXZ5 has a higher tensile strength and higher rigidity than its predecessor MXZ4 chain.
520MXZ5 will also come with a new less tacky grease which is less likely to attract dirt and debris.
Please note that MXZ5 and MXZ4 connecting links are NOT interchangeable! You must use MXZ5 connecting links on MXZ5 chains and MXZ4 connecting links on MXZ4 chains.
