EK/PBR 420SR Chain Kit 11/50 - Standard Sprocket
This EK Chain 420SR kit includes a chain, an 11-tooth sprocket, and a 50-tooth sprocket (standard sprocket) designed for small urban motorcycles. Built around the SR series, it combines robust construction with lasting flexibility: the plates undergo a specific heat treatment that enhances wear resistance while maintaining the necessary flexibility for smooth operation in the city.
Regular installation and maintenance (tension, lubrication) are essential to get the best performance from the kit. Check compatibility with your model before ordering — this kit is specifically listed for machines like the BETA RRT 50 MOTARD TRACK (2012 - 50 cc).
