Brake linkage servo arm for Promoto-MX

This 20T servo arm set is manufactured from 7075-T6 aluminium as an RC-scale replacement for Promoto-MX machines produced for LOSI. It installs at the servo output and connects to the brake linkage so you can refine lever geometry and braking feel without swapping electronics.

Supplied as a matched pair for standard dual-link arrangements on Promoto-MX bikes. Confirm fit against the listed LOSI models before fitting. Basic fitting requires removal of the original arm, correct spline indexing and reusing the factory fasteners for secure attachment.

Packing includes

  • Servo arm - 2pcs

Original Name / Part No:

LOS261013,LOS262009

Compatible Models

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

Does the arm work with all Promoto-MX brake setups?

The arm is intended for the LOSI models listed in the compatible models box. Match your servo spline count to ensure a secure fit.

How does the alloy affect braking?

7075-T6 alloy increases rigidity and reduces wear at the spline interface, giving steadier brake linkage movement under repeated use.

What should I watch for during fitment?

Ensure the arm seats properly on the servo spline, do not over-tighten screws, and verify linkage clearance across steering and suspension travel.
