EK/PBR 520M3 Chain Kit 14/50 - Ultra-light Sprocket
Specially developed for motocross, this EK CHAIN kit includes a 520M3 chain and a 14/50 sprocket/crown ratio. Gold/gold finish for a sleek look and increased visibility on the transmission. Designed to minimize friction while ensuring good resistance to traction and abrasion in demanding conditions.
Ideal for off-road bikes and motocross sessions where weight and the responsiveness of the secondary drive matter. The ultra-light aluminum crown reduces unsprung mass and contributes to better engine feel without compromising the transmission cadence. Remember to check and adjust the tension after installation, lubricate regularly, and inspect the condition of the crown teeth at the end of the season to maintain performance and safety.
