Motorcycle Racing Chain - O-ring Type

• Our motorcycle chain are made of high-quality alloy steel, with small hardness tolerance after heat treatment to achieve higher toughness, tensile strength and impact resistance.

• The O-ring type chain used special pin, which used chrome alum coating and carbonizing process increasing the surface hardness from HV0.2 750 to HV0.2 2000, which is same with the abrasion standard from Japan, reducing the elongation from abrasion of the chain.

• O-Ring/X-ring Chains achieve permanent lubrication sealed between pin & bush which ensure with longer lifetime and minimum maintainance. X-Ring safely sealed lubrication inside the chain during its lifetime and let the chain run much smoothly, engaged better than O-Ring chain.

• With Solid bush, high quality pin material and 4-sides riveting.

• O and X-ring chains are wider than comparable standard chains, but in general the same sprockets can be used.
