The MX030 kit is an aftermarket aluminium upgrade for LOSI PROMOTO-MX motorcycles. Fabricated from 7075-T6, the knuckles and pull rods cut down flex at the steering joint and help deliver more predictable steering under load while remaining straightforward to service.
This set fits LOSI 1/4 PROMOTO-MX motorcycle RTR models, including PRO CIRCUIT variants, and includes larger inner bearing seats plus four 4x10x4 bearings for direct replacement. Intended for RC use only.

Ideal for racers and hobbyists looking to firm up front-end feel, the kit provides metal replacement parts and bearings to improve steering consistency without modifying motor or electronics.
