ELITE - Includes TT2782 12.5mm SILVER rotor. Setup critical, SILVER rotors are a special extra strong material and can be damaged by excessive heat from over-gearing and over-timing. 
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.
