We finally got some semblance of decent snow last week and I got to ride the new pro 163. WOW. I actually took off from a dead stop on a steep hill and went straight up gaining speed the entire time! ive never been able to do that on that particular hill with any previous sled and for what its worth Im SOLD. This sled is definitely startin to live up to the hype. I can see where these guys have been complaining about the lack of stated horsepower, but the sled does what it needs to do, regardless of what they say the actual horsepower is. We ride with a guy with a 220 HP King Cat and there wasnt anyplace he could leave me behind. We'll see if the really deep stuff makes a difference, but as far as first impressions go, SOOOOOO GLAD I BOUGHT ONE!!!!
