EK/PBR 520MRD7 Chain Kit 14/50 - ultra-light sprocket: a transmission kit designed for motocross, combining a high-performance 520 chain and an ultra-light aluminum sprocket. The golden finish on both components provides a sleek look for your motocross while minimizing friction and offering good abrasion and traction resistance in severe riding conditions.
Designed to withstand the demands of off-road and competition, this chain kit is aimed at motocross riders looking for a lightweight and responsive transmission. Remember to check the tension, clean and lubricate the chain regularly after muddy rides, and verify compatibility with your model before installation. Compatibility examples: Kawasaki KDX 250 (years 1983–1985).
