EK CHAIN — EK/PBR 520M3 Chain Kit 14/51 (Ultra-light Sprocket)
Designed for off-road and motocross competition, this 520M3 chain kit combines a gold-treated chain and an ultra-light aluminum sprocket. Resistant to tension and abrasion, it aims to provide reliable transmission while reducing unsprung weight thanks to the lightweight sprocket — an advantage for riders seeking mechanical responsiveness and lower inertia when entering and exiting corners.
