The MX030 kit offers a metal aftermarket option for the LOSI PROMOTO-MX chassis. CNC-style 7075-T6 aluminum construction reduces joint deflection and extends service life compared with factory plastic pieces, while remaining accessible for routine maintenance by hobbyists.
Included are upgraded inner bearing seats and four 4x10x4 bearings for straightforward replacement. This set is intended for LOSI 1/4 PROMOTO-MX motorcycle RTR models, including the PRO CIRCUIT version, for RC use only.
