Moose Offroad Hard-Parts Front Sprocket (ref. D26-5163-13CRMO) — Designed for Enduro and Supermoto practices, this 13-tooth sprocket with a 520 pitch provides a robust solution for the front transmission of your off-road motorcycle.

• Material: High-strength Chromoly steel, machined to limit deformation under load and withstand repeated impacts.
• Finish: Heat-treated and then nickel-coated for improved corrosion resistance and a lubrication effect at the chain/sprocket contact.
• Internal splines: Precision machining for maximum contact with the secondary shaft and optimal distribution of transmission forces.
• Quality control: Each sprocket is checked using a three-dimensional measuring machine (CMM) to meet manufacturer specifications.
• Position: Front — 13 teeth, natural colour.

Ideal for racing on rough terrain or modified asphalt sessions, this sprocket is aimed at riders looking for a durable part that adheres to OEM tolerances. Check the available space around your secondary shaft before installation if you opt for a diameter different from the original. Common compatibilities: GAS-GAS EC 300 (2015 models - 300 cm³) and Two Wheel Dirt, ADV and ATV applications depending on variations.
