I've got a 04 Sportsman 500 H.O. and it seems to hold it's own in the mud and on the trail. They are a bit heavy (700 lbs), but i'm only 120lbs and i can throw the bike around no problem. The bike rides awesome, four wheel drive works great. I've topped mine out at 70 mph on a gravel road. I'm not saying anything bad about Honda's cuz i know a lot of people that have them and i like them a lot...but i love my sportsman
