EK/PBR 520SRX2 Chain Kit 13/48 - Ultra-Light Sprocket
The SRX series from EK CHAIN offers a clear compromise between durability and controlled pricing, highly appreciated by off-road riders. Designed for motocross, this 520SRX2 chain kit consists of a 520 chain with 114 links and an ultra-light aluminum rear sprocket, paired with a 13-tooth front sprocket and a 48-tooth rear sprocket for a suitable ratio for Husqvarna WR 250 and similar machines.

The aluminum sprocket reduces the weight of the rear transmission compared to a steel sprocket, without promising unverified effects: it simply helps to lighten the rotating part. The SRX chain retains EK's proven construction, designed for the demands of off-road riding, jumps, and frequent accelerations.
Top compatibilities: Husqvarna WR 250 (2012, 2013, 2014). This kit is a practical option for those completely replacing their drivetrain with components suited for motocross/enduro use.
