EK/PBR 420SR Chain Kit 12/47 - Standard Sprocket
Specifically designed for urban use and small displacement motorcycles, this EK CHAIN kit combines a 420SR chain and a 47-tooth steel sprocket mounted with a 12-tooth pinion. The SR series features a design that maintains the flexibility of the plates even after long mileage, thanks to a specific heat treatment of the plates, enhancing durability and wear resistance.
This kit is aimed at urban riders looking for a robust transmission for their 50cc motorcycle. Installation, tension adjustment, and regular lubrication will optimize the longevity of the drive train. Check the number of teeth and pitch before installation to ensure compatibility with your machine.
