This front wheel axle is specified for 1/4-scale LOSI PROMOTO-MX motorcycles and supplied as a dedicated RC spare. The axle is produced from imported medium carbon steel, then blackened and hardened to enhance surface durability and wear resistance while keeping compact hobby-grade dimensions.
Technical notes: the hexagonal head is chosen to ensure firm driver engagement during removal and installation, reducing slippage risk when servicing the front wheel position. Inspect axle seating, bearing preload and runout before operational use.
