This MX-scale side cover set is CNC-oriented 7075 aluminium hardware engineered for LOSI Promoto-MX 1/4 RC motorcycles. The matched two-piece components replace factory plastic covers to deliver improved local stiffness and enhanced abrasion resistance at common impact and wear zones.
The pair is supplied left and right to align with Promoto-MX chassis mounting locations, allowing a direct-fit replacement using existing attachment points so suspension and drivetrain geometry remain unchanged.
From a maintenance and setup perspective the MX013 panels provide a robust mounting surface that helps preserve chassis reference lines after impacts, making them suitable for aggressive track use and abrasive surfaces where plastic parts typically shorten service life.

The MX013 side covers are a precision-focused durability upgrade for Promoto-MX owners who require stiffer chassis edges and predictable fit; verify alignment during installation and inspect mounting points after initial testing.
