the #1 seller is honda, #2 is polaris (thats because a lot of lawn mower and tractor deals sell them too) # 3 is yamaha, #4 is suzuki, # 5 is arctic cat. honda is probably the toughest, but also has the stiffest suspension and rides the roughest, will also cost the most, arctic cat and polaris have the smoothest suspension,, arctic cat has the most ground clearance, susuki vinson (500) was named 4 wheeler of the year last year by a couple of magazines.. lot of good choices for you to make
