Be aware . . . anyone and everyone who has an ATV will probably, most naturally, tell you why their brand ATV is the best . . . because of course none of us would want to say I bought a complete piece of junk for $7,000 and it has been a terrible waste of money.
That said . . .
First . . . a confession . . . I am an unabashed Honda lover.
Second . . . another confession . . . while I am president of an ATV Club, the truth is I do far more work with my ATV than I do trail riding . . . even though the road I live on is an ATV Access Route. I really would love to do more trail riding, but the truth of the matter is my ATV was bought mostly for work . . . the pleasure riding is just the icing on the cake.
I have a 450 Honda Foreman which I use to plow my driveway, do yard work, haul the spliter around and haul out wood . . . this past summer in fact I used my ATV to twitch out several 4 foot loads of wood (3-5 4 foot wood in various diamaters x 3) . . . so what I am saying is that this ATV is a real work horse.
Newer Foremans now = 500 cc engines. But, anything 350-400 cc should be fine for what you need . . . but of course as guys we always believe bigger is better!
My Foreman offers the solid rear axle vs. independent rear suspension -- I find it to be less tippy feeling compared to ATVs with IRS (the trade off being it is not as smooth for trail riding.) My ATV also has a lower center of gravity compared to many ATVs -- again, good for work and riding on uneven ground, but it means it also doesn't have quite as much ground clearance . . . although if the truth be told a couple of inches generally doesn't make that much of a difference.
I have never had a heating issue . . . but this is also air-cooled with a fan assisting the cooling process when needed. This ATV is built for work . . . quite honestly, I sometimes wish I had a little more top end speed when trail riding, but this is offset by a low and slow first gear which can really haul.
As I said, I suspect most ATVs 300 cc+ would fit the bill . . . the Honda does have a few negatives in my opinion. First, it doesn't offer a lot of new tech or fancy doo-dads -- Honda always seems to be lagging behind other manufacturers when it comes to "new" tech as it seems as though their corporate philosophy is stick with what works until customer demand is such that they will start to change. Second, Hondas seem to be pricey. Finally, they might not have the vaunted "true" 4WD -- although the truth of the matter is I have never felt that not having "true" 4WD is an issue . . . the few times I have been stuck in a mud hole while trail riding I simply had to apply my front brakes or rear brakes and all four tires would hook up.
My honest opinion . . . check out the Foreman . . . but also check out some of the other manufacturers.
