Features

ESJOT Front Sprocket 520 – Ref. 50-32109-14S

Front sprocket made of 16MnCr5 steel designed for the demanding needs of enduro, motocross, and supermoto. This 14-tooth sprocket with a 520 pitch features a hardened and precisely machined tooth profile, engineered to withstand wear while maintaining reliable geometry on the drive shaft.

Material: 16MnCr5 steel with high-quality hardening
Teeth: 14 — 520 pitch (compatible with 520 chain)
Position: Front (countershaft)
Finish: Natural
Machining: CNC automatic lathes and precision broaching
Tolerances: concentricity and runout less than 0.1 mm
Design: lightening holes and additional threading for weight optimisation
Manufacturing: 100% Germany

CNC machining and broaching operations ensure a precise fit on the shaft, limiting vibrations and premature wear. Ideal for performance-oriented setups and sustained off-road outings — particularly compatible with YAMAHA YZ 125 (2025/2026), GAS-GAS EC 450 F Racing (2015), and YAMAHA YZ 125 Monster Energy Edition (2025).
