That seems to be changing since that is the biggest selling segment in atv sales. Can Am upped the ante last year when they redid the 500 V twin Rotax at 46 HP. Polaris fired back with 44 from the 570. Arctic Cat has that 443cc Kymco rocket that would smoke many 500 cc class quads. Gonna be interesting.

 

I also have heard of some wire harness problems on the xp models.i think that leaves me with the 570 eps.i have been loyal to Polaris the last 10 years but I haven't ruled out switching brands,possibly a grizzly.

 

I have 7000 miles on my 2012 550. All original except the tires...Best mac hine I have ever owned..

 

Almost 2000 miles on mine and still original parts. Has been airborne several times. It is always well greased and lubed. I ride from the Oregon dunes to the High desert. Has been very reliable.
