This MX-scale side cover set is a 7075 aluminium upgrade made for LOSI Promoto-MX 1/4 RC motorcycles. The two-piece covers replace the original plastic parts to add local stiffness and better abrasion resistance where the chassis commonly takes wear.
The left and right pieces are supplied as a matched pair that line up with the Promoto-MX chassis mounting points. Fitment is intended to be a direct replacement using existing attachment locations so suspension and drivetrain geometry remain as stock.
For tuning and upkeep the covers give a durable load bearing edge that helps keep chassis lines true after impacts, which is useful when running rough tracks or hard-pack terrain where repeated contact can abrade standard plastic covers.
LOS261014
The MX013 side covers are a practical, serviceable upgrade for Promoto-MX owners who want tougher chassis edges without altering ride geometry; verify alignment during installation and recheck fasteners after the first run.
