Polaris is making an art of getting rid of the rotating mass. one reason the Poo feels so light and has good response.
I want to see the other brands with belt drive system. Power to weight, rotating mass, two to the big marvels of a good sled.
Just my thoughts,
So back to the HP if there is only 4 HP differance in these 3 brands, what is the trick.
XP Summit said it, getting the power to the snow. The weight is not a big deal, but the Rotating mass is, IMO ..
I love it when marketing has come to fishing storys on there HP and there Weight.
