Moose Racing 12 teeth Gearbox output pinionRef : ME03554A / 12122178

Front Sprocket MOOSE OFFROAD HARD - PARTS (Manufacturer Ref: 26-4108-12CRMO) designed for off-road motorcycle transmission. Machined from high-strength chromoly steel, this 12-tooth sprocket with a 520 pitch is intended for enduro and motocross riders seeking a robust part that meets OEM specifications.

• Material: Heat-treated chromoly steel
• Finish: Nickel coating for improved corrosion resistance and lubricating properties
• Teeth: 12 (520 pitch)
• Position: Front / secondary shaft
• Quality control: Each sprocket checked on a three-dimensional machine (CMM)

The internal splines are machined to ensure maximum contact with the secondary shaft and optimal distribution of transmission forces, thus limiting the risk of premature play. The heat treatment combined with the nickel coating helps reduce deformation and wear during intensive use on rough terrain.

Compatible with a wide range of Two Wheel Dirt, ADV, and ATV applications — examples of motorcycle references: YAMAHA YZ 426 F (5SF) 2002, WR 426 F (CJ) 2002, WR 400 F (5GS) 2002. Before ordering, check the available space if you opt for a sprocket larger than the original to avoid any contact with the crown or casings.
