Rolon "BPR KIT" brass-plated chain sprocket kit for the Royal Enfield Classic 500 and Bullet 500, made up of a brass-plated chain, a front sprocket and a rear sprocket. Both inner and outer link plates are brass plated by an advanced plating process for rust and corrosion protection against moisture, monsoon roads and long-distance touring, and the chain has enhanced wear resistance due to quadruple sealing. Precision-engineered sprockets and chain spread the load evenly for smooth, efficient power transmission and reduced vibration. The sprockets offer high fatigue strength, and the rubberized front sprocket reduces noise and acts as a damper. Designed for the Bullet and Classic 500 range with OEM-level fitment, the kit suits city, highway and rough-terrain riding. Its lustrous gold-toned brass finish complements classic Royal Enfield styling.
