This is a motor that is even more tightly regulated than other "spec" motors. A Roar 21.5 motor is a spec motor.

The idea is to buy it and race it. Not to send it to "Stator Stu" to get it tuned up somehow (???), or to change parts for additional money, or whatever other foolishness.

The idea was to take some of the motor madness out of the class, but it seems like it never stops.
