Promoto-MX 1/4 Front Rear Axle Set Medium Carbon Steel MX025FR by GPM  [MX025FR]

Replacement Wheel Axles for Promoto-MX

This axle set is a drop-in replacement for LOSI Promoto-MX 1/4 motorcycle models, carrying the model number MX025FR. Both front and rear axles are produced from imported medium carbon steel and are treated with blackening and hardening to enhance surface wear resistance during scale riding and display use. The hex-shaped head helps reduce driver slip while fitting or removing wheels, simplifying workshop tasks.

Role and fitment: intended as direct wheel position replacements to restore correct retention and alignment after wear or impact, and to support basic setup and tuning on scaled dirt-bike models. Installation requires the matching hex driver and a post-fit check of axle tightness and wheel seating to ensure safe running.
