The JT SPROCKETS ultra-light aluminum sprocket 1793 - 520 is designed for replacement or adjustment of the gearing on roadsters. Machined from aerospace aluminum 7075-T6 (Ergal), it offers a balance between lightness and strength while maintaining the standard profile compatible with chain 520.
This sprocket is aimed at riders who want to lighten the final drive without changing the chain pitch. Its Ergal design reduces the mass of the part compared to steel sprockets, which affects the rotational inertia and the perceived responsiveness of the transmission. Suitable for road use and gearing modifications, it is ideal for a simple and clean replacement on machines that accept a 520 sprocket.
