Tekin's SPEC-R brushless motors are professional racing power plants designed to squeeze out every ounce of power available and propel you to the finish line first. Based on the widely popular GEN3 motor platform, the SPEC-R brings new technology to the racetrack. Tekin's ULR (ultra low resistance) design puts top shelf performance in your RC racing vehicle using proprietary specifications and the highest grade materials available for ultra smooth control across a wide powerband. ULR technology and a Yellow High Strength Rotor  make the SPEC-R lineup of motors the premium choice for stock racing. Drop a SPEC-R motor in your chassis and leave your competition in the dust.

Available in 21.5T 17.5T, 13.5T and 6.5T, there is a SPEC-R motor available for your racing class.  Combine the SPEC-R motors with the RS Pro Black Edition ESC for the ultimate in Ultra Low Resistance systems.

**Please note that the 6.5T SPEC-R is designed for 1/12 Spec classes and should only be used with the RSX PRO speed control.**
