*Gen 4 Motors with a stuck rear Endbell. They run just as good as a standard motor and are set at the optimum timing for most applications. However, adjusting the timing takes significant force or in some cases is not adjustable at all. The cost is less than what a replacement rotor and sensor board ($80 value) cost so they can also be considered upgrade or spare parts for other Tekin motors you own.*
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.
