EK/PBR 420SR 12/48 Chain Kit - Standard Sprocket by EK CHAIN: a chain kit designed for urban roads, intended for small displacement bikes and daily use. The SR series incorporates a heat treatment of the plates that preserves the flexibility of the chain even after long service, while increasing the strength and lifespan of the components.
This kit is aimed at riders looking for a robust and easy-to-maintain chain for urban and compact use. The SR design limits the stiffening of the links after mileage, facilitating mechanical monitoring and regular lubrication. The standard steel crown ensures mechanical compatibility and longevity suitable for the sprockets of small motorcycles.
Common Compatibilities: suitable for the 50 cc models listed as examples — RIEJU SMX 50 (2004), RIEJU MRX 50 PRO (2004), and RIEJU MRX 50 (2004). Always check the pitch and the number of teeth required for your machine before installation.
