Designed for sports use and racing, this ESJOT rear sprocket provides a robust and precise transmission component for a 520 pitch chain. Made from high-strength C45 steel and treated with a zinc coating, it offers a durable finish suitable for the demands of intensive use on road or track.

The tooth profile is machined using the Diamond Cut 2.0 process, and the sprocket benefits from a specific surface treatment recommended by ESJOT to limit premature wear. Its rigorous construction ensures precise geometry, essential for smooth transmission and a sharp response to engine torque — key factors for sporty riding and strong starts.

Suitable for sports bikes such as Ducati Panigale (e.g. Panigale V4 R, 1299, 1199 depending on applications), this sprocket is intended for riders looking for a reliable replacement part to maintain or optimise their gearing. Please check compatibility with your model before installation.
