I did it today ! I wasnt sure but I did . I bought my first 4 stroke :thumbsup: I bought a 2007 Apex RTX . I PICK IT UP MONDAY. It took a long time to decide , it was between a Ski Doo Blizzard 800 or Apex rtx. I just guessed at the end . My next 100 miles on the APEX will be very hard for me not to tap it wide open on a lake . I had borrowed a 05 rx1 one season so Im used to the 4 stroke and it really grew on me. Now my wife is getting the sticker for theSXR that say " This isnt my husbands sled " .
