This alloy upgrade set is built for the Promoto-MX platform produced for LOSI, using 7075 aluminium to provide higher rigidity than typical stock parts. It focuses on durability and chassis response while retaining the model's original setup.
The parts are intended as direct replacements at common wear locations on the dirt bike chassis. Fit these alloy components into the factory mounting points to keep steering geometry and fit unchanged.
Use the set as part of a staged tuning plan where selective alloy pieces stiffen targeted areas, improving consistency over rough terrain without altering drivetrain or chassis dimensions.
This set is ideal when you want an all-in-one alloy replacement for Promoto-MX models to extend service life and sharpen chassis feedback while avoiding chassis modification.
