All EK Chains motocross chains utilize our CRH pin treatment which provides an extremely hard outside coating and softer inside to increase strength and reduce chain wear. Exclusive to EK Chains, the Chormium Carbide pin surface coating also offers superior impact and shock absorption while reducing oxidation caused by natural elements.
Because these chains do not use sealing rings. you will benefit from reduced friction and increased performance making them ideal for sprint racers. Similar to the RXO line without the Quadra-X Ring seals, these non-sealed chains save nearly half a pound versus their sealed counterparts.
The 415RR also features lightening holes in the side plates to reduce the chain's overall weight by 3% without compromising tensile strength. These holes also extend the service life of the chain by dissipating heat and helping reduce dirt and mud build up.
