The Polaris pulled it because it weights more, that simple. The difference of power or tires between the two quads does not matter, they both have more than enough to smoke the tires and are both getting equal traction on gravel. If it was on pavement, power and tire choice would come into play.

Weight is key, thats why Polaris wins. Put a big 500 lbs ride on the Praire and a 200 lbs rider on a the Polaris, the Praire wins.

But stock for stock, equal rider weight the Polaris wins.

 

actually it was on tar and my brother weighs probably close to 175lbs less than my buddy..
