Product details :

Features

RFX Race Sprocket 12 Teeth — front sprocket machined for 520 transmission, designed for demanding motocross riders. Made from cemented alloy steel and heat-treated, this RFX sprocket offers high wear resistance thanks to a cementation hardness of 60 Rockwell and CNC machining with tight tolerances.

Ideal for replacing the stock front sprocket on motocross machines, it maintains the standard geometry for easy installation on the gearbox output. Some models in the range are drilled for weight reduction without compromising strength, which reduces unsprung mass while maintaining transmission safety.

Number of Teeth: 12
Chain Pitch: 520
Material: Cemented alloy steel
Color: Silver
Version: Standard
Machining: CNC with high tolerances

Common compatibilities: designed for the motocross universe. Often fitted on TM RACING MX 125 (2021, 2022) and TM RACING MX 125 RACING (2012). Manufacturer reference: FXFS 80-12 55ST. A reliable choice to maintain the longevity and consistency of your front transmission.
