Moose Offroad Hard Front Sprocket - Parts (ref. D26-4167-13CRMO)

This drive sprocket is designed for offroad practices (Cross, Two Wheel Dirt, ADV, ATV). Machined from high-strength chromoly steel, this 13-tooth sprocket with a 428 pitch combines robustness and precision for reliable transmission on the secondary shaft.

• Material: Chromoly Steel, machined to limit deformation under load.
• Teeth: 13 (428 pitch) — designed for compatibility with 428 chains.
• Position: Front (countershaft sprocket).
• Finish: Heat-treated and then nickel-plated to improve corrosion resistance and contact lubrication.
• Splines: Internal splines machined for maximum contact with the secondary shaft and optimal force distribution.
• Quality control: Each sprocket is checked on a three-dimensional measuring machine (CMM) to match OEM specifications.
• Colour: Natural (metal)

This sprocket is particularly suitable for YAMAHA TT-R 125 LWE models (2015–2017) among other applications. Before ordering, check the available space if you opt for a sprocket size different from the original. Installation and maintenance should follow manufacturer recommendations to ensure proper chain engagement and regular wear of the teeth.
