I have a 2007 Suzuki Kingquad 450 4X4. It is a great machine for the money with IRS and EFI. No cranking and choking my machine. Just hit the starter and it is going and that was in some -20 degree weather out on the ice. It is full sized and has plenty of power to haul myself and plenty of gear all over the frozen shores of Lake Champlain. I had it up to 55 and it was still climbing but since I had chains on the rear wheels I figured I was going way too fast. Great ATV and it was mine new for less than 6 grand.
