after owning almost a dozen atv's in the past, i would say that honda is hands down the most reliable, but if your looking for a big displacement, my money would be down on the yamaha 700efi (has power steering) also quite a few of the 09 hondas are offering the power steering which is a very nice feature,but todays market in quads all seem equal, just test ride alot and get what machine you feel most comfortable on it all i can say, currently have a 99 honda foreman es 450 and it has been bullet proof since owned never had to replace anything as far as parts go
