EK/PBR 520SRX2 Chain Kit 12/50 - Ultra-Light Sprocket
Designed for motocross, this EK CHAIN kit combines a 520 SRX2 chain with a 12/50 sprocket/crown set. The gold finish on the chain provides a polished look and quick identification on the bike. The kit is aimed at riders looking for a drivetrain ready to withstand off-road use while remaining easy to maintain.
The SRX2 chain benefits from EK CHAIN's reputation for good value and its popularity among motocross riders. The ultra-light aluminum crown reduces the weight of the sprocket-crown assembly without compromising the practicality of installation and maintenance. The kit is compatible with many motocross models, including the KTM 300 EXC TPI ERZBERGRODEO (2020–2022).
Ideal for restoring the drivetrain or replacing a worn set, this kit offers a complete and coherent solution to get back on the track quickly.
