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.

Light, durable, almost perfect. Designed for motorcycles with a displacement of up to 1000 cm³.

The UW ring is the latest sealing technology developed by RK engineers.

It guarantees a low resistance to friction, does not heat the chain and thus ensures its long service life.

Three sealing points fully protect the chain from corrosion.

- RK recommended racing chain for athletes and super athletes

- 520UWR was developed for the race track.

- 7% lighter than comparable 520GXW chain, with similar tensile strength

- RK technology: ultra-thin UW rings minimize weight and reduce friction losses

- Design concept similar to that of the MOTO GP chain

- Highlights the immediate response to acceleration thanks to the rigid design of the inner glie
