This MX-scale chassis side cover set is an aluminum upgrade intended for LOSI Promoto-MX 1/4 RC motorcycles. Manufactured from 7075 aluminum, the two-piece set replaces molded plastic covers to add local stiffness and improved abrasion resistance at common wear points on the chassis.
The parts are supplied as a matched left and right side set designed to align with the Promoto-MX chassis mounting locations. Installation focuses on simple replacement of the original covers using the existing attachment points, keeping fitment consistent with stock geometry so suspension and drivetrain settings remain unchanged.
For tuning and maintenance the covers provide a durable mounting surface that helps keep chassis edges true after impacts, and they are useful when running rough tracks or hard-pack conditions where repeated contact can abrade standard plastic components.

The GPM MX013 side covers are a straightforward, serviceable upgrade for Promoto-MX owners who want a tougher chassis edge without changing ride geometry; verify fit before final tightening and inspect mounting points after first run.
