LOSI PROMOTO-MX 25T 7075 Aluminium Servo Horn MX2025T by GPM  [MX2025T]

7075 Aluminium 25T Servo Horn for PROMOTO-MX

This 25T servo horn is machined from 7075 aluminium and specified for RC-scale LOSI PROMOTO-MX motorcycle models. It replaces the original plastic horn at the servo output to limit flex under braking and cornering loads while remaining straightforward to fit during routine setup and service.

The part engages the servo output splines and acts as the direct connection between the servo and the brake or steering linkage. The aluminium horn preserves servo alignment under repeated stops and aggressive transitions, helping to maintain consistent brake and steering response without changing electronics or servo configuration.

Fitting is standard for spline-style arms: remove the existing plastic horn, locate the 25T spline, secure with the factory retaining screw, and confirm full travel prior to running. Fine adjustments to linkage length and horn angle may be required to restore neutral steering and accurate brake engagement.
