SUPERSPROX STEEL CHAIN & SPROCKET KITS

Supersprox/EK Chains and sprocket kits are a great way to grab everything you need in one kit. 
Supersprox has been supplying the highest quality sprockets since 1959 and has grown to be one of the largest sprocket manufacturers in the world. Founder Roger Maughfling, who was extremely passionate about motorcycles, began producing sprockets as supply was lacking for the makes and models he needed. Over the years Supersprox has been set as the industry standard.

SPROCKET FEATURES

• C-45 high-quality steel
• Long-life, anti-corrosion silver finish
• Carbide cut, CNC machined teeth
• Exceeds OEM specifications
• One of the light steel sprockets on the market

All EK Chains motocross chains utilise 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 Chromium Carbide pin surface coating also offers superior impact and shock absorption while reducing oxidation caused by natural elements.

The 520MRD7 also features lightning 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.
