Does anyone have any compartive information on the new Sportsman 500 from previous models? I've never owned a Polaris, but am thinking seriously about purchasing the new Stealth 500 for my wife. She really likes the ride and handling of the Polaris over other bikes she tested. The mechanic at the dealer told us they have less problems with the 500 than any other model. Just want to make sure I am making a good decision here. Thanks for any feedback!
