ESJOT Rear Sprocket (manufacturer ref. 50-32065-49) — 520 black sprocket made of QSTE460 steel, 49 teeth, rear position. Designed by ESJOT to meet OEM requirements, this sprocket features concentricity and run-out tolerances of less than 0.1 mm and a surface-treated finish to withstand the stresses of transmission.
Dedicated to Trail/Adventure, Enduro, Roadster, Cross, Quad, Sport/Racing, and Supermoto riders, it fits on 520 transmissions where robustness and precision of the tooth profile are essential. The machined tooth profile using the Diamond Cut 2.0 process and the specific coating contribute to controlled wear under intensive usage conditions.
Frequent applications: KTM SMR 450 (2025), HUSQVARNA 701 ENDURO (2024), and GAS-GAS EC 300 (2023). Ideal for riders looking for a reliable replacement part and smooth transmission, whether on the road, in dunes, or on trails. Always check compatibility with your model before installation.
