SPEC-R2 21.5T GEN4 PRO Brushless Motor (TEKTT2689P)

SPEC-R2 21.5-turn GEN4 PRO brushless motor is a high-performance racing motor built for SPEC-class competition. It pairs a hand-picked stator and sensor board with a 12.5 mm silver rotor, a rotor material chosen for strength and efficiency that benefits from careful setup to avoid heat damage from over-gearing or over-timing. This motor is designed to deliver strong speed and torque with minimal fade as the race wears on.

Designed for race use, it features 60-degree adjustable timing, a SPEC Racing–specific design, and a CNC-machined 6061-T6 billet aluminum heat sink can. It uses high-purity copper windings and neodymium sintered magnets to maximize energy conversion and is sensored-system ready. Anodized endbell plates boost corrosion and wear resistance, while high-RPM bearings and an oversized front bearing support reliable performance. ROAR-approved and legal in major racing bodies, this motor meets the demands of serious competitors who need consistent power across heats.
