We only sell the Renthal Works 520 R3.3 O Ring . These have replaced the old R3 Chain.

After a lot of practical research on the roads and green lanes of Devon, these chains have proved to give exceptional service. Also fits Yamaha WR250R and WR250X models

It is a 118 link chain which fits all the combinations of TTR250, WR250R/X and WR250F sprockets that we sell although it will need some links taking out for smaller sprocket sets. This is easily done with a chain breaker. Guide to shortening a chain here.

This 520 o-ring chain is designed for the extreme rigours of off road use.

The pack contains both a rivet (soft) and a split link plus rubber gloves and sticker.

NB The original chain and sprockets on a Raid are 428 so this chain will only fit if the sprockets are upgraded at the same time to match.

An excellent addition to your tool kit!

Most chains are too long to use out of the packet to allow for accurate adjustment, so this is the perfect tool to cut your chain to the correct length required for your TTR.

Works well with soft links but you will need to grind the heads off of hardened pins before use e.g. where you are shortening a chain. Make sure that you remove both pins equally so as not to bend the backplate.

Easy to use and no loose parts to lose.

Frame guard or "tensioner" kit - this fits to the frame above where the chain runs and protects the frame from a loose chain. 

They usually get very worn over time and are worth replacing before they wear through.

The fiche diagram below shows the parts included in the kit and where they bolt to the frame.
