Front Sprocket MOOSE OFFROAD HARD - PARTS (Ref. D26-5159-13CRMO) — Designed for off-road use, this high-strength chromoly steel sprocket provides mechanical durability suited to the demands of motocross and off-road outings. Its natural nickel finish protects against corrosion while improving sliding performance with the chain.

• Material: Chromoly Steel, heat-treated and tempered to limit deformation in case of impact.
• Teeth: 13 — pitch 420, front position (countershaft).
• Machining: precise internal splines specified to maximize contact with the secondary shaft and distribute transmission forces.
• Surface Treatment: nickel coating against corrosion and for better sliding with the chain.
• Quality Control: each sprocket is inspected using CMM (coordinate measuring machine) to meet OEM tolerances.

This sprocket is suitable for Two Wheel Dirt, ADV, and ATV applications. Changing the sprocket alters the gearing and engine behaviour; check the available space and exact compatibility with your model before installation. Examples of commonly affected motorcycles: KTM SX 65 (2026), HUSQVARNA TC 65 (2026), and GAS-GAS MC 65 (2026).
