The utv will stay in the utv class and run the utv series. There is absolutely no reason to mix the 2 together. Why ppl keep comparing the 2 is mind blowing. It's like saying well my 10 car beat most of the class 1 cars so now I am a class 1 car. It's a Polaris utv. Not a class 10 . There is rules on what motor you can use and the Polaris motor is not one of them. They can port and do whatever they want to in there class our motors are sealed stock motors. Not the same rules not a class 10.
