Reedy Sonic 540-M4 Modified Motor 4.5

The Reedy Sonic 540-M4 Modified Motor 4.5 delivers a linear powerband and strong mid-range feel in a lightweight, rebuildable brushless motor design. Its inner bearing is integrated into the can to improve rotor alignment while reducing noise and vibration, and the shortened motor design helps centralize chassis weight.

The CNC-machined can, aluminum end cap, optimized air cooling, and low-resistance silver-plated solder tabs support efficient operation. A balanced, high-strength rotor, adjustable timing, and precision stainless steel ball bearings complete the motor's competition-focused design.
