a little advice from a racer/rider. im a 4 wheeler fanatic, and had a 97 banshee, an ds650X, and a 86 250r that was modded big time. all 3 were about the best thing you could get in their class. i traded off with my buddies alot at the track and on the trail. they had, 400ex, raptor, 450 yamaha, 400 kawi, and polaris predator. now all these are good machines, but ill rank them anyway
1. ds650x unbelieveable power, unreal suspersion. little bigger than all the others, but buttery smooth all day long, excellent build quality
2 banshee, dont let anyone tell you its unreliable, fast, very comfortable, ride it year round, no changes at all
3 250r, dont really need to explain this
4 polaris predator, suspension is the best, cheap, 500 4stroke
4 400 kawi, very cheap, on same scale as polaris. snappier though
5 450 yamaha, i absolutly love this bike, but its spendy, and the stock shocks are complete garbage. tourqe up the a**
6 raptor, fast, comfortable, cheaply built though. excellent used buy, they are dirt cheap
7 400ex, slow, boring. dont get one
