Note: The Renthal R3-2 chain is supplied with both an easy-fit split master link and a superior solid-pin rivet master link which matches the durability of the chain. Note for installing X-ring chains: As X-ring chains are wider than standard roller chains, when fitting an X-ring chain to a motorcycle that was fitted with a non O-ring chain as original equipment, it is essential to check that there is proper clearance of the engine cases near the countershaft sprocket and any other places of close contact. Failure to do so could result in damage to the chain and motorcycle and could ultimately cause the chain to fail.
