i think its going to take a lot for polaris to top maverick, even in HP there going to have to get back to drawing board, focus, advance and test. its not as simple as changing something on the engine on the xp. in any case, canam would top that, then polaris then canam and hopefully along teh route some of the other oew's jump in. the problem is not who has most hp, 101 hp, 103, 105,etc. for 95% of riders its not about squezing the last ounce of hp out because they dont race, except for a few fun ventures against there buddies. the true racers who do it most of the time, well the mod hell out of what ever they buy so its no where stock or close to out of the box.
so then you have to look at other avenues to what you like or want, form, fit and function, the cockpit area, comfort,etc plays into who is the best. there canam has major trumped polaris, major! heck a lot of xp owners go buy the shock set up you find out of the box on the canam commander, with canam its standard. with xp your out a couple thousand dollars extra for great shocks. even the canam commander 1000 will tie, or in some cases beat the xp out of the box. xp was a sport model, commander is a rec/utility model, not even same class and yet the commander ties and beats the sport model of polaris was impressive in a lot of cases. it would not matter to me if the xp come out at say 103,105 hp. i would still take maverick due to form fit and function, quality and what you get and its potential/
