RK UWR:
The 520 UWR chain is the highest technological achievement in the RK range.
The chain was specially developed for professional road racing on closed tracks.
Lightweight, durable, almost perfect. Designed for motorbikes with an engine capacity of up to 1100 cm³.
The UW ring is the latest sealing technology developed by RK engineers.
It guarantees low frictional resistance, does not heat up the chain and thus ensures its long service life.
Three sealing points protect the chain completely against corrosion.
- Racing chain recommended by RK for sports and super sports bikes
- 520UWR was developed for the race track.
- 7% lighter than the comparable 520GXW chain, with similar tensile strength
- RK technology: Ultra-thin UW rings minimise weight and reduce friction losses
- Similar design concept to the MOTO GP chain
- Emphasises the immediate response to acceleration due to the rigid design of the inner link
Available options:
Sprocket 15 - 16 teeth
Sprocket 40 - 41 - 42 - 43 - 44 - 45 - 47 teeth
