Ive had snowmobiles and atvs by all of them. Im kind of a hypocrite because im the flag waving buy American type but atvs and snowmobiles too Yamaha is just a step ahead of everyone in fit and finish and the only one that comes close in reliability is honda but I think Yamaha still has a slight edge. You want a brute strong atv that will never leave you stranded and will still be running as good 20 years from now buy a grizzly. They may not be the fastest in there class but there fast enough and are dead reliable. Son in law owed me some money so gave me a 500 Polaris sportsmen in exchange. Its a joke compared to the grizzly. Maybe they've improved since 08. they better have! Brother in law has two fo the honda ranchers one older and one two years old. He will tell you flat out they don't hold a candle to my grizzly in any way. Like comparing a model t pickup to a new 3/4 ton pickup. For one thing I don't have a clue why anyone would want a atv that you had to shift gears manualy on anymore. About compares to a 3 on the tree! he took them both up and traded them on a 500 grizzly last summer. good thing about a honda is they do hold there value. I was surprised what the dealer gave him for them. Im holding out. I want a new one but im not unhappy with mine and am kind of waiting for yamahas rumored twin cylinder griz. they need something to compare power wise to the big Polaris's and cat's an 800-1000cc v twin would have me opening up my check book.
I have a Honda 4Trax from 90 or 91. Never have done anything but change the plug, oil, filters, and battery. Only use it for three months in the fall so it sits under a shelter most of the time. I finally gave it to my hunting club. Now kids rid it mostly.
