I've riden the 420 AT and I like it ,nice light lil machine with the same power as the 450 Foreman in my view. The thing I love most is the in and out of 4x4,Its a manual shift in and out instead of electronic. The only thing I didn't like was no speedo on the manual shift model. It also needs a adjustable rear suspention,Found the single shock set up is too soft and will really squat when riding 2-up. I'd own one!
