Features

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.

Color: Gold / Gold
Pitch: 520
Number of Links: 118
Relative Lifespan (for 100 links): 450
Sprocket Material: Aluminum (ultra-light)
Weight: 1.36 kg / 100 links

Designed for a 14-tooth front sprocket and a 51-tooth rear sprocket; ideal for motocross bikes such as the KTM 350 XC-F (2020, 2021, 2022). Be sure to check the tension and lubricate the chain regularly to maximize its longevity and performance in muddy or dusty conditions. Manufacturer's reference: Not provided.
