Speed Pasion Rotor Tuning???
 

I would like tune my speed passion 13.5. Can I use other manufactures rotors in my speed pasion? What size comes stock? What happens with different sizes? Help???

Lager diameter rotor means more power in lower rpm but you loose top rpm.
Smaller rotor means more top rpm but lower power is less.
Try to shim your rotor as close to the rear end where the sensors are.
This will help to let the motor respond better on power.
I do not know if other makes of rotors will fit.
