You probably know if you saw my post (new sled new direction) that I picked-up a 2010 XTX. The reasons are as fallows,long track; better on rough trails,better off trail,four stroke engine will last longer(MORE MILES) than 2 stroke, sounds cool too, no more injection oil, Yamaha builds a quality piece, Factory rep. sugested taller winshild & deflectors,(got those) and maybe mountain skis if going off trail alot, will be looking at those eventually. sorry about the run-on sentance.
