Product details :

Features

EK/PBR 520SRX2 Chain Kit 12/50 - Standard Sprocket by EK CHAIN: a kit designed for motocross that offers a good compromise between performance and longevity. Built to withstand the demands of challenging terrains, this kit combines a 520 pitch chain with a 12-tooth sprocket and a standard 50-tooth sprocket — ideal for restoring the transmission of your off-road bike.

Usage: Motocross / amateur competition
Configuration: 12-tooth sprocket / 50-tooth sprocket (standard sprocket)
Number of links: 114
Color: Gold/Gold
Sprocket Material: Steel
Pitch: 520
Weight: 1.54 kg for 100 links
Durability Index: 3300 (reference for 100 links)

The SRX series is known for its balance between cost and performance: the gold finish facilitates visual wear detection, and the steel sprocket ensures good resistance to shocks and abrasion. This kit is suitable for models like GAS GAS EC 125 RACING (2013–2015) and other machines equipped with 520. To ensure optimal lifespan, follow the maintenance intervals, tension, and lubrication recommendations provided by your workshop or manufacturer’s manual.
