Tekin Pro4 BL 6D 1400kv, 540, 5mm shaft

The Tekin Pro4 BL 6D 1400kV 540 brushless motor (TT2509) is engineered for the demands of 4 Wheel Drive Short Course performance. Borrowing proven architecture from Tekin’s T8 1/8th scale platform, this 4-pole, 12-slot design delivers the torque and smooth, controllable power delivery that 4x4 short course trucks require. The 1400kV wind is designed to complement 2S–6S LiPo power systems, offering a broad setup window for varied tracks and conditions.

Built for efficiency and durability, the Pro4 features a CNC-machined 6061-T6 aluminium heatsink can to help manage temperatures, neodymium sintered magnets, and high-purity copper windings for maximum energy conversion. High RPM ABEC5 oversized bearings support the rotor for smooth running and longevity, while the rebuildable construction makes routine maintenance straightforward. A dual-plug sensor wire harness ensures easy integration with both sensored and sensorless systems, and the 5mm shaft provides robust drivetrain engagement.
