XRU Chain - Superbike Racing Chain
520 XRU Sealed Sprint/Race chain - UW Ring (Similar multi-point seals to X-Ring, but triple barrier compared to X-Rings double barrier).
- 520XRU chain was designed for professional MotoGP racing. Featuring UW-Ring seals.
- XRU is a lightweight professional racing chain.
- The UW seals reduce friction while maintaining optimal horsepower delivery from the start of the race to the end.
- Developed in collaboration with MotoGP and World Superbike teams to produce the ultimate racing chain.
- Application of a sealed chain on races can minimise the elongation of the chain which maintains the meshing precision between chain and sprocket, keeping high transmission efficiency throughout the race.
RK Racing Chains are developed specifically for track usage and strictly not for daily street usage. They are designed to be strong and light to emphasize instant respond on acceleration however the maximum chain life is approx. 700[km] and less depending on usage condition.
Main Points
- For Racing up to 1000cc
- RK UW Seal Ring
- Ultra Thin ring to minimize chain weight and friction loss
- Use for Superbike Road Racing and MotoGP™
TRU Chain - 250cc Amateur Race Chain
RK’s TRU Racing Chain Series uses the UW-Ring Ultra Thin Seal, where the thickness of seal is less than 50% of the common seal, making it possible to design a Sealed Chain with the weight of a Non-Sealed Chain.
