EK/PBR 520SRX2 Chain Kit 17/40 - Standard Sprocket
Designed for riders seeking a reliable and economical chain kit, this EK CHAIN 520SRX2 combines the SRX2 chain with a 17-tooth sprocket and a standard 40-tooth rear sprocket. The SRX series is known for its balance between performance and value, making it ideal for road use on roadsters and lightweight sport bikes.
Compatible with many roadsters, this kit is particularly suited for APRILIA RS 125 (2005 models: Replica, GP Compet, Extrema). For optimal longevity, follow the installation, tensioning, and lubrication recommendations from your manufacturer. Installation is done like any 520 kit: check the condition of the bearings, tensioners, and replace the sprocket and rear sprocket simultaneously if necessary.
