They are right at the limit width wise, maybe a little too wide. You will give your wrists a beating where I ride, a possible broken bone even. I'd rather have a reverse capable quad also, just a personal opinion of course. If you look at my u.p. pics you'll see why a reverse could come in handy, my friend on the 400ex had to get off and turn it around quite a bit there. The power band favors the top end quite a bit on those, a hmf or another low end promoting pipe and lower geared sprockets might be a good idea for trail riding with them, and also some shorter than stock arms. I'd go with one of the new 400's for trail riding even though I favor yamaha, you can't go wrong with any of those.
