Tekin’s SPEC-R2 brings next-level performance to SPEC racing classes. Improving on the original SPEC-R design, we revamped and refined the stator, rotor and materials used to increase both speed and torque while providing minimal fade during the late stages of the race. The SPEC-R2 is a hand-crafted, high-performance racing motor that is ready to hit the track right out of the box.


The SPEC-R2 improves upon the original GEN4 SPEC-R design, bringing higher performance to the track. We put in the R&D and testing time and the result is a motor that just flat out performs. With SPEC carpet classes gaining in popularity, we needed a fresh update that puts down the torque and power racers have been asking for. Put the SPEC-R2 on the track and it speaks for itself.
