RK 525 ZXW XW-Ring chain with 110 Links in a choice of colour
The ZXW chain is the top performing chain in the RK Street range. It was developed from the GXW series of chains to meet the needs of high-powered and extreme Superbikes of 1000cc and above and is characterised by an extremely high tensile strength. It makes it an excellent choice for the large capacity adventure bikes, where the longevity and strength will allow consistent use on and off road for mile on mile.
Due to the shape of the XW-rings, the chain is sealed at six sealing points, this helps avoid lubricant loss from the centre of the chain and prevent dirt ingress.
Rk chains are available in various colours including Steel, Gold, Black Line, Blue, Green, Yellow, Orange and Red. Not all colours are imported in to Europe. If you're looking for a colour not listed, please ask.
