Features

EK/PBR 420SR 13/53 Chain Kit - Standard Sprocket by EK CHAIN. A complete kit designed for urban and city use: 13-tooth sprocket / 53-tooth sprocket, pitch 420, and 134 links for an installation suited to small displacement motorcycles.

Series: SR — plates heat-treated to maintain flexibility and strength even after prolonged use.
Materials: steel chain / steel sprocket.
Number of links: 134.
Pitch: 420.
Weight: 0.75 kg (for 100 links).
Durability index: 200 (reference 100 links).

The heat treatment of the SR series plates enhances wear resistance while maintaining good chain flexibility — essential for frequent starts and stops in the city. This kit features a standard steel sprocket and a classic profile chain, easy to maintain and compatible with 420 transmissions.

Ideal for lightweight motorcycles and 50cc city bikes, it is particularly suitable for RIEJU MRT 50 SM PRO (2013), RIEJU MRT 50 ENDURO (2013), and RIEJU MRT 50 PRO (2009) models. For optimal longevity, adhere to the lubrication and tension recommendations provided by the manufacturer.
