I just got an 06 Outlaw 500 IRS. I got the 500 for the reliability but it has some pretty good get up and go. I am not into top speed, just like to come out of the corners fast and be able to wheely. The 500 sure will. It has the original tires with screws in it for the snow.
I just ordered a full set of ITP Holeshot GNCCs for it, can't wait to get those on.
