I see that they sell a lot of different rotors for the revtech motors.

What is the difference on the rotors.? 12.3 12.4 12.5. How can I tell what rotor my revtech has in it now....I bought it used.

Thanks.

is the size of the rotor, some rotors have color coded rings on them, get a pair of calipers and measure the rotor, then you will know. generally, 12.3 is going to have more rpm, 12.5 is going to have more torque

There is no 12.4 rotor for trinity rotors, a rotor that is below 12.4 is considered a 12.3 rotor. A rotor larger than 12.4 is considered 12.5.
