EK/PBR 520MRD7 13/50 Chain Kit - Standard Sprocket — a chain kit designed for the demands of motocross. The golden 520MRD7 chain combines strength and optimized glide to minimize energy loss and withstand the challenges of muddy and rocky terrains. Ideal for riders pushing their machines off-road and in competition.
This chain kit is designed to maintain reliable transmission on demanding courses: its finish reduces friction and the steel sprocket provides abrasion resistance. To ensure longevity and precision, regularly check the tension, clean, and lubricate after each muddy or dusty ride.
Common compatibilities: SUZUKI RM‑Z 250 (2024, 2025, 2026). Always check the number of teeth and pitch before installation for a perfect fit.
