Designed for regular torque exchanges and typical acceleration phases of roadsters, this kit is aimed at owners of models such as APRILIA TUONO 457 (2025), APRILIA RS 457 (2025), and APRILIA RS 457 (2024). The reinforced steel sprocket provides better wear resistance compared to standard sprockets, while the riveted attachment ensures a permanent connection once properly installed. Professional crimping is recommended to ensure the safety and longevity of the assembly.
Ideal for restoring or optimising the maintenance of the transmission, this kit offers a practical and robust solution to achieve a well-tensioned chain and consistent transmission behaviour.
