The EK/PBR 520SRX2 17/45 chain kit - standard sprocket is a transmission set designed for off-road riders seeking a reliable performance/value compromise. Made by EK CHAIN, this kit includes a sprocket, a rear sprocket, and a chain with a pitch of 520 for a complete overhaul or a fresh start of your transmission. The steel/steel finish and the steel rear sprocket make it a robust option for off-road use.
Designed to withstand the demands of the terrain, this kit is particularly suited for trail/cross applications where regular maintenance (tension and lubrication) and checking for wear on the links are essential to preserve the longevity of the transmission. Easy to install for primary ratio adjustments, it is suitable for both routine replacement operations and track adjustments.
Compatibility examples: KTM 620 EGS (1995–1997) and other machines that accept a 520 pitch with a 17-tooth sprocket / 45-tooth rear sprocket.
