if you have the width required no 4-wheeler will go where the side by sides will
RR, yer obviously not from Northern Minnesota... I have an 03 Bombardier Traxter Max, but there's no way it or your side by side is going to take me where my 83 Honda Big Red 3 wheeler will in this area... I also have a Yamaha 500 Phazer for when the snow gets too deep... I've run the Bombardier in 10 inches of wet snow, but the Phazer handles it much better.
As far as noise goes, Kawasasaki's are notoriously famous for there engine noise (at least they used to be) I'm not sure if they make any wheeler with a gas engine that's real quiet.
