Features

EK/PBR 520M3 Chain Kit 13/51 - Ultra-light Sprocket

Designed for off-road and motocross riders, this EK/PBR 520M3 chain kit combines a high-performance 520 chain with a 13-tooth sprocket and an ultra-light 51-tooth rear sprocket made of aluminum. The gold/gold finish resists visual wear from the track while facilitating visual inspection for wear. Ideal for those looking to reduce unsprung weight without sacrificing the mechanical grip necessary for competition.

Type: 520M3 Chain Kit (13/51)
Number of Links: 114 (to be shortened if necessary for fitting)
Color: Gold / Gold
Sprocket Material: Ultra-light Aluminum
Weight: 1.36 kg for 100 links
Relative Lifespan: 450 (index for 100 links)

The chain is optimized to minimize friction while providing good tensile strength and abrasion resistance, crucial parameters for muddy and rocky terrain. Installation and tension should be checked regularly; proper lubrication extends lifespan. Common compatibility: Yamaha YZ 250F (2011–2013) and other motocross machines equipped with 520.
