Note for installing O-ring chains: As O-ring chains are wider than standard roller chains, when fitting an O-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.
Note: Image is for reference ONLY, actual product will vary based on fitment and selection.
Some Helpful Tools: Try the Motion Pro Chain Breaker & Riveting Tool or BikeMaster's Heavy-Duty Chain Breaker & Rivet Tool to make removing your old chain and installing your new chain as easy and painless as possible.
