This full set of upgrade parts is a dedicated RC-scale replacement kit designed for the Promoto-MX platform produced for LOSI, using 7075 aluminium for improved stiffness over typical stock materials. The kit is intended to provide straightforward component swaps that focus on durability and chassis response rather than altering geometry or drive characteristics.
Parts in this set serve as direct replacements and reinforcement items for common wear points on the dirt bike chassis. Installation is meant for model-level maintenance and tuning: users should remove the corresponding factory pieces and fit these alloy components in the same mounting locations to retain original fitment and steering geometry.
As an upgrade set, the parts support iterative tuning approaches where adding selective alloy components increases rigidity in targeted areas, enabling more consistent handling on rough tracks while keeping the model within standard RC scale performance expectations.
Choose this set when you need a complete alloy replacement suite for Promoto-MX models to improve part longevity and chassis feedback without changing fitment or requiring chassis modification.
