Suzuki King Quad 450 has it all: EFI, IRL, liquid cooled, Push button 2WD and 4WD with locker diff and weighs 600 pounds. Lots of power at a decent price and a great ride.
The problem I have with the 450 KQ is the 4WD selector. You have to take your right hand off the throttle to engage it and that o me is bad if your into some deep crap and want to pop into 4WD from 2WD. You would more than likely have to or come to a stop and sometimes that isn't too good.
The MSRP has been dropped on the Polaris Sportsman 500EFI which I would bet would tear most all the others up in a tug of war.
