ivv bin racing a while now, the 04-05 yfz are complete junk and dont handle anywhere near the ltr with the 48 wide suspension but the motor on the ltr is not that fast i have a can am ds450 and me and my freind(has an ltr) where on the street he took of as hard as he can so i did i could have smashed right into him. If u have a high budget i would look at the 09 only yfz450r,ktm450sx,canamxmx. i would personally get a can am conforte,reliablity is great, the motor has crazy power, i rode the the new yfz450r and wasnt to inpressed with the power the handling was pretty nice, and then the ktm just has stright up balls power deffently the fastest 450 beat my can am by about 2 legths and the handling is sick with the ohlines
