EK/PBR 420SR 11/51-126 Chain Kit - Standard Sprocket
Complete chain kit designed for the transmission of small urban motorcycles. The SR series focuses on heat-treated plates to enhance wear resistance while maintaining good flexibility of the chain. This kit combines a 420 non-sealed chain with a standard steel sprocket, suitable for daily use and lane splitting in the city.
For urban riders, this kit offers a robust and straightforward solution: the absence of seals makes replacement easier but requires regular maintenance (cleaning and lubrication) to ensure longevity and proper functioning of the transmission. The heat treatment applied to the plates improves abrasion resistance without adding weight to the chain, maintaining a responsive feel at the sprocket and sprocket.
