EK/PBR 420SR Chain Kit 12/50 - Standard Sprocket
Designed for urban use where responsiveness and reliability matter, this EK CHAIN 420SR kit combines a 420 chain with a standard 12/50 sprocket/crown set. The SR series features a design that maintains the flexibility of the chain even after prolonged use. The plates have undergone a specific heat treatment to enhance durability and wear resistance without promising unverified performance.
Ideal for mopeds and small displacement bikes in urban environments, this kit is particularly suitable for BETA RRT 50 models (Motard Track, Motard Racing, Motard - 2012). To maintain its longevity, regular maintenance is recommended: tension checks, appropriate cleaning, and lubrication. Reliability and robustness are guaranteed for your city rides and daily sessions.
