Specifically developed for today's 1,000cc to 1,400cc, high-performance sport machines. High-quality components coupled with a factory-greased seal ring ensures superior rigidity. High-tensile steel used throughout the chain components; larger pins mean loads spread out over wider area, resulting in longer life and more strength. Specially controlled heat treatment means tougher material and more durability. Average tensile strength of 10,420 pounds. Max engine size of 1,300cc. Includes rivet master link.
