ESJOT front sprocket for 525 pitch transmission, designed for demanding riders who want a reliable and durable part for their roadster. Machined from 16MnCr5 steel with surface hardening, this 18-tooth sprocket combines mechanical precision and wear resistance for intensive use, including in competition. The lightening holes and integrated reinforcements reduce mass without compromising strength, while maintaining fit on the shaft. CNC manufacturing and high-precision broaching ensure tight tolerances: concentricity and axial runout below 0.1 mm. 100% made in Germany.

Ideal for original replacement on roadsters (e.g. certain versions of Aprilia 850 Mana/GT listed), this sprocket meets ESJOT's high OEM standards. The choice of the number of teeth affects the gearing and torque/peak behaviour of the engine: check compatibility with your model before installation. Product intended for road and track use depending on installation and regulations.
