This CNC-machined 7075 aluminium front bulkhead is a sturdy replacement for Promoto-MX dirt bike platforms. Built to reduce flex and protect mounting points that often suffer when using standard plastic parts, it offers a more robust interface for the fork assembly.
The component is made for hobby use on LOSI Promoto-MX chassis and the compatible RTR models listed in the compatibility block. It helps maintain steering alignment and supports the front fork setup during higher stress runs.
Fitting is typical for Promoto-MX service: remove the stock bulkhead, inspect fasteners and bearings, then install the new aluminium part using the original hardware. After fitting check fork alignment, steering travel and re-torque fasteners to the recommended values.
