This MX-scale side panel set is an aluminium upgrade tailored for LOSI Promoto-MX 1/4 RC motorcycles. Fabricated from 7075 aluminium, the pair replaces moulded plastic panels to improve local stiffness and reduce wear at common contact points on the frame.
The components are provided as a left and right matched set that align with the Promoto-MX mounting positions. Installation is a simple swap using the existing attachment points so stock suspension and drivetrain geometry is retained.
In workshop and track use the panels give a firmer mounting surface that helps maintain chassis edge integrity after knocks, especially useful on rough circuits or abrasive surfaces that quickly wear plastic parts.

MX013 side panels are a straightforward durability upgrade for Promoto-MX riders who want stronger chassis edges without changing handling; check alignment and retorque after initial runs.
