ESJOT Sprocket — Manufacturer reference: 50-29059-41
Designed for demanding users, this ESJOT rear sprocket combines materials and precision machining for a reliable fit on roadsters and sports bikes. Made from QSTE460 steel, it features a specific surface treatment and a tooth profile machined using the Diamond Cut 2.0 process, ensuring consistent geometry and regular wear under intensive use conditions. Concentricity and runout tolerances of less than 0.1 mm for stable transmission behaviour.
Ideal for replacing the original crown on road or racing setups, it is aimed at riders seeking precision in chain-sprocket coupling and longevity of the final drive. Compatible with several Aprilia 1100 models (Tuono V4 and RSV4 2021) — check model/year compatibility before installation.
