I am tired of riding the edge and am considering a 900 rmk, My sled is a 03 sno check 800 159, considering a 05 900 151 anniversary. What can I expect on the ride differances, Sidehilling, straight up pulls,Will the 05 do every thing the 03 will do? or Better? I ride usually 4500 to 7000 ft mountains,hills, trees,boondocking, not much of a fan of the Himark. My 03 has about all the bolt on slp items there is, has been rebuilt on the crank,and clutches, Any way there is nothing wrong with my sled I just want to move on.The only issue I am concerned about the 900 is the vibration I hear everybody talking about.Thanks Steve
