EK/PBR 520SRX2 13/52-118 Chain Kit - Standard Sprocket by EK CHAIN. Designed for motocross enthusiasts seeking a relevant compromise between performance and cost of use, this kit is based on the SRX series, known for its balance and regular improvements.
This kit includes the essential components to renew the transmission: standard pitch 520 chain, 13-tooth front sprocket, standard format 52-tooth aluminium sprocket, and 118 links for a ready-to-use installation. The finish and choice of components aim for simple installation and broad compatibility with modern motocross machines.
The QX-Ring seals help to limit lubricant loss between the links and preserve the integrity of the parts under varied conditions. This kit is aimed at motocross and enduro riders who want a ready-to-ride chain, suitable for both training and dynamic outings. It is particularly suitable for KTM 450 XCF-W (2026), HUSQVARNA FE 450 (2026), and GAS GAS EC 250 F (2025) models according to the gear ratios.
