This MX-scale side cover set is an aluminium upgrade designed for LOSI Promoto-MX 1/4 RC motorcycles. Machined from 7075 aluminium, the two-piece set replaces factory plastic covers to add local rigidity and resist abrasion at frequent impact zones.
The parts are supplied left and right as a matched pair to suit Promoto-MX chassis mounting points. Fitting is a straightforward replacement using the original attachment locations so suspension and drivetrain settings remain consistent with stock setup.
On rough tracks or hard-pack surfaces the covers provide a tougher contact surface that helps maintain chassis edge geometry after impacts and reduces wear to plastic components during repeated use.

The MX013 covers are a no-nonsense upgrade for Promoto-MX users who need better abrasion resistance without changing handling; always check alignment and re-torque after the first outing.
