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.
