Chain RK 520 UW'Ring hyper reinforced gold
Hyper-reinforced RK 520 pitch chain with ultra-thin U'Ring O-rings. Considered the lightest on the market with a weight of 13.8g/link (only 0.1g heavier than the MXZ series), the MXU series allows you to have all the advantages of an O-ring chain (prevents debris from entering the internal pins of the chain) and those of an O-ring free chain (light weight while guaranteeing its strength).
Specially designed for off-road enduro and motocross. The chain is gold coloured and comes with a quick release.
In order for you to be able to close your chain kit, we offer you several suitable chain rivet/unrivet tools, and if necessary, we also offer to close your chain ourselves.
Select from our 3 best sellers your suitable chain rivet/drivet tool for your motorbike chain (either for hollow pin end attachment - like for RK or JT chains - or for solid pin end attachment - like for Tsubaki or IRIS chains).

We can close your chain before shipment by our technical team who will use the appropriate tools to crimp the attachment of your motorbike chain, with the guarantee that the work will be carried out in accordance with the rules of the art (we also provide a spare crimping attachment).
ATTENTION: Some motorbike models do not allow the fitting of a closed chain to the transmission (please check the technical specifications of your motorbike), in which case you will have to order an open chain and crimp it yourself once installed. This closed chain option can also only be chosen when the chain kit is in the original gear or with a maximum of 2 teeth difference compared to the original (e.g. +1 tooth on the sprocket and -3 teeth on the sprocket). In fact, with greater differences, we cannot guarantee 100% of the recommended chain length calculation. The recommended chain length on the website is based on information provided by the factories. The customer should always check the length of his chain before ordering a closed chain.
