Replace or adjust the gearing of your transmission with the JT Sprockets JTA478.42BLK sprocket, designed for riders looking to reduce unsprung mass without sacrificing load-bearing capacity. Machined from aerospace-grade 7075-T6 aluminum (Ergal), this ultra-light sprocket offers a good balance of strength and weight for road outings and roadster use.
Suitable for interventions on sprockets and crowns, it allows you to modify the gearing to favor acceleration or top speed according to your setup. Its design facilitates installation, and the machining of the mounting points adheres to manufacturer specifications for precise positioning.
Examples of compatible motorcycles (to be verified according to year and installation): Kawasaki Ninja ZX-6R 636 (2020-2025) – ideal for those looking to refine the responsiveness of their transmission on the road. In case of doubt, consult your workshop or the manufacturer's technical sheet before installation.
