The EK/PBR 520MRD7 13/48 chain kit is designed for motocross riders who want a reliable and responsive transmission without frills. Built to reduce friction while providing good resistance to traction and abrasion, it meets the severe demands of muddy terrains and repeated jumps. The gold finish adds a polished visual touch and makes it easier to visually check the condition of the chain between rides.
Designed for motocross use, this kit combines robustness and modularity: steel sprocket for endurance on the track, and a 520 pitch sprocket and chain for a torque/speed compromise suitable for 125cc engines and above. Ideal for riders who replace their transmission piece by piece before an off-road season.
