The EK/PBR 520MRD7 13/48 Chain Kit by EK CHAIN is designed for motocross riders seeking a lightweight and robust setup for cross outings and competition. Comprising a chain with a pitch of 520 and an ultra-light aluminum sprocket, this kit prioritizes weight reduction without sacrificing durability against abrasion and traction encountered in off-road conditions.
Designed to minimize friction while providing good wear resistance, this chain/sprocket combination is suitable for the specific demands of motocross: repeated jumps, dirt projections, and constant stress. Standard mounting and adjustment required — check the number of links and tension before the first ride.
