Chain EK MRD

Motocross Race Chains
The MRD7 Series is EK Chains 7th generation motocross specific racing chain. Featuring a revised pin design and CRH chromium carbide coating for maximum wear reduction and performance. A total weight reduction of 3% has been achieved through lightening holes on the inner plates. This also aids in service life as heat is dissipated more quickly and dirt builds up less.

Supersprox Front Sprocket

Supersprox countershaft sprockets are factory-team spec parts (used in WSBK, MXGP, and Rally) made from ultra-durable, carbon-impregnated SCM-435 (18HGT) steel for maximum strength. They feature a lightened design with radial holes or slots, an ultra-hard surface layer to reduce chain friction, a black oxide coating to prevent corrosion, and self-cleaning grooved teeth on off-road models to extend chain and sprocket life.

Supersprox Racing Steel Sprockets in sleek black finish are designed for both street and off-road motorcycles, developed on world endurance race tracks to meet high-performance demands. They feature laser-cut weight-reduction design to lower rotational mass, extra durable teeth for longer life, and tri-zinc electroplating to prevent rust and corrosion.
