7075 Aluminum 25T Replacement Servo Arm for PROMOTO-MX

This 25T replacement servo arm is machined from 7075 aluminum and sized for RC-scale use on LOSI PROMOTO-MX motorcycle models. The aluminium arm replaces the stock plastic horn at the servo output to cut flex under braking and steering loads while preserving simple installation for regular hobby maintenance and setup.

The component mounts to the servo splines as the mechanical interface between the servo and the brake or steering linkage. The stiffer aluminium horn helps the servo keep alignment during repeated stops and sudden throttle-to-brake transitions, producing more consistent brake feel without altering electronics or servo programming.

Installation follows standard spline-style procedures: remove the factory plastic arm, align the 25T spline, tighten using the original retaining screw, then check the full travel. Adjust linkage length and horn angle as needed to restore neutral steering and correct brake travel.

Packing includes

  • Servo Arm 25T - 1pcs

Original Name / Part No:

LOS261013

Compatible Models

  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06000
  • LOSI-1/4 PROMOTO-MX MOTORCYCLE RTR, FXR-LOS06002

Will this fit the stock LOSI PROMOTO-MX servo spline?

Yes. The arm matches the 25T spline used on the listed PROMOTO-MX models and is intended to replace the standard plastic horn at the servo output.

Can I expect reduced flex with this alloy arm?

Yes. 7075 aluminum offers greater stiffness than the original plastic, helping to keep linkage geometry stable under braking and steering loads.

Do I need extra hardware to fit it?

No extra parts are normally required. Reuse the servo's original retaining screw and verify fit and motion after installation.
