Well yesterday I was very suprised. My parents are demoing an 2012 teryx 4 750. Well for grins and giggles we decided to do some straight line comparison. In the viking I had me and my little boy. In the teryx it was two adults and two kids. granted the teryx had 4 people in it. But off the line I pulled the teryx by about a half a length. We stayed like that till about 35 mph then he started to pull back around me. That would be the power of the v twin comin into play there. But I figured he would of just blew my doors from the get go. So I was pleasently suprised.
