This MX-scale side cover set is a 7075 aluminium upgrade for LOSI Promoto-MX 1/4 RC motorcycles. The matched two-piece set replaces moulded plastic covers to deliver improved local stiffness and abrasion resistance at frequent wear areas on the chassis.
The left and right components align with Promoto-MX chassis mountings and are intended to fit using the original attachment points. That keeps suspension and drivetrain geometry unchanged while upgrading durability.
These covers provide a tougher mounting surface for track use, helping to keep chassis edges straight after impacts and reducing the rate at which plastic panels abrade on rough or hard-packed surfaces.

MX013 side covers are a sensible durability upgrade for Promoto-MX owners seeking tougher chassis protection without altering handling; confirm fit before final tightening and recheck after the first session.
