Chain | Chain Type | Avg. Tensile Strength | Maximum Rated Displacement | Weight (pounds per 100 links) | Master Link Type |
---|---|---|---|---|---|
D.I.D 420V O-Ring Chain | O-Ring | 3,560 pounds | 250cc | 1.60 | Clip (RJ) |

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.

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.
D.I.D's top quality O-Ring chains are quad stake riveted with solid bushings for superior strength and long life.
