I think the Warrior would win. My dad has a 400 scrambler that only beats me by about 1-2 lenths and my clutch is just about done. Ive never racer a 500 before but yours is a 4x4 which makes it much slower/heavier and I've heard from many people/places that the 400s spank the 500s

 

a friend of mine has a warrior and he thought it was so bad ***,i beat him so bad on my 400 scrammy it wasnt even funny,i bet i could have won in reverse..
