Tekin’s SPEC-R brushless motors are engineered for award-winning performance. Utilizing the best materials available we redesigned the SPEC-R to cut weight while reducing resistance, resulting in a purebred Spec racing machine. On Road or Off, the SPEC-R handles all situations, providing smooth power and control across all RPMs when you need it. The SPEC-R is competition performance with the speed you need to win. Pair with an RS PRO Black Edition for the ultimate in SPEC Racing Equipment.


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