Motor Overview


Tekin's SPEC-R brushless motors are engineered for acclaimed performance. Utilizing the best materials offered we redesigned the SPEC-R to cut weight while decreasing resistance, resulting in a purebred Specification racing maker. On Roadway or Off, the SPEC-R manages all scenarios, offering smooth power and control throughout all RPMs when you need it. The SPEC-R is competitors performance with the speed you need to win. Pair with an RS PRO Black Edition for the ultimate in specification Racing Equipment.



The GEN4 motor line is a completely new ground-up design. We put in the design and test time so you can minimize your lap times. The new stator is accuracy stamped and pressed, increasing performance and decreasing resistance. Our motors are hand-wound with high pureness copper wire and machined from 6061-T6 aluminum. Entirely tunable with optional rotors and re-buildable, the new GEN4 SPEC-R motor is a premium performance power plant for the major racer.
