The MX030 knuckle and pull rod kit is an aftermarket RC-scale upgrade made for the LOSI PROMOTO-MX platform. Machined from 7075-T6 aluminum, these parts reduce flex to deliver firmer steering inputs and improved durability while keeping installation straightforward for regular hobby maintenance.
The set fits LOSI 1/4 PROMOTO-MX motorcycle RTR models, including the PRO CIRCUIT variant, and includes larger inner bearing seats plus four 4x10x4 bearings for direct replacement. Use on RC models only.

For builders wanting a metal steering upgrade for the PROMOTO-MX, this kit replaces the stock plastic knuckles and pull rods and supplies bearings to firm up steering and support suspension tuning without changing motor or electronics setups.
