Product details :

Features

EK/PBR 520M3 13/51 Chain Kit - Ultra-Light Sprocket by EK CHAIN: a specific kit for motocross riders who want to lighten the transmission without sacrificing strength. Designed for the demanding conditions of off-road riding, this kit combines a 520 chain with an ultra-light aluminum rear sprocket to reduce unsprung mass and improve the bike's agility during angle changes.

Color: Gold / Gold — finish that withstands the visual aggressions of the terrain.
Pitch: 520 — compatible with standard motocross transmissions.
Number of links: 114 — length ready to be adapted for installation.
Sprocket / Sprocket: 13 teeth / 51 teeth — ratio oriented for motocross.
Sprocket material: Aluminum — ultra-light to reduce inertia.
Weight: 1.36 kg for 100 links — useful data for calculating weight savings.
Relative lifespan (100 links): 450 — indicator provided by the manufacturer.
Manufacturer reference: Not provided.

This kit prioritizes weight reduction and longevity in off-road use: chain treated to limit wear from abrasion and aluminum sprocket to reduce unsprung weight. Ideal for CRF 250 R (2007–2009) and similar motocross machines. Regular installation and maintenance recommended to maintain performance in competition or training.
