This kit is aimed at urban motorcyclists looking for a robust and easy-to-maintain chain for city riding. Ideal for standard transmission setups, it is particularly suitable for models such as the APRILIA RX 50 (2018 - 50 cc) when compatible in terms of sprocket/rear sprocket ratio. After installation, check and properly adjust the chain tension and ensure the tightness of the fasteners before putting it into service.
Product delivered in standard configuration: sprocket, steel rear sprocket, and 134-link chain — a reliable solution to restore the transmission to working order without technical complications.
