Sigma ORS O-Ring Steel Chain - Low maintenance

As this O-ring chain is manufactured with high technology and based on long experience, Tsubaki bring you a chain that simply has no equal. This heavy duty chain is ideal for the current generation of Motor Bikes with high power rating. When this chain reaches the operational temperature it is running smoothly and has less articulation friction.

• Tsubaki chain has perfectly cylindrical bushings and is pre-stretched for decreased initial elongation and increased wear life.
• Quality quad-staked riveting of the pin heads ensures maximum resistance to push out force.
• High viscosity grease is vacuum injected internally to dissipate heat and shock load.
• Super Seal O-rings surround shouldered and projected bushings to eliminate power robbing friction and seal dirt out.
• Sigma’s heavy duty construction gives it exceptional strength and wear resistance and has been tested and proven on race tracks all over the world.
