I have a Honda Foreman which I bought second hand, it's 450, and I think it's a 1999. It's got 9000km's (5000 miles) on it. Runs like a champ and climbs like a goat.

Nothing fancy it just works and works.

Over the years I've driven Suzuki, Polaris, CanAm, Yamaha, Honda, and Arctic Cat. The only quad I've been stranded on - twice - were Yamaha Grizzly's. Lot of people swear by them but after the last time which was a 7 mile walk back to camp I don't believe I would consider owning one. Other than Yamaha I think they are all reasonably good or maybe I just had bad luck.
