This 7075 aluminum front bulkhead is a scale replacement designed for Promoto-MX dirt bike platforms. Machined from aircraft-grade aluminum, the part focuses on adding front-end rigidity and offering a tougher mounting surface where stock plastic components commonly wear.
Intended for hobby use on LOSI Promoto-MX chassis and compatible RTR kits listed in the compatibility box, the bulkhead supports the front fork assembly and helps keep alignment under the kind of load encountered in aggressive trail or track running.
Fitting is straightforward for anyone familiar with Promoto-MX maintenance: remove the original front bulkhead, inspect and reuse the existing fasteners and bearings where appropriate, then fasten the new aluminum unit using the factory hardware. After installation verify fork alignment and steering travel, then re-torque to the chassis maker's recommended values.
