i dunno about that being to tall or big for a 400ex, i have never rode one. i am 5'10" and about 215 and i ride a blaster and a banshee [img]/wwwthreads_images/icons/smile.gif[/img] if i can ride a blaster i guess anyone can ride anything!
Im 6-1 and i have real LONG legs and i dont feel comfortable on it. my legs are real close to the fenders and it seems like i cant move around alot. go to the dealer and test ride on and see how it feels.

It is not about "WHAT" you ride, It is about "IF" you ride.
I am 6"6 and weigh a mere 265lbs. I own both a 2001 400EX and a 2001 Raptor. I have no problems riding either quad and actually prefer the 400EX for certain types of rides over the Raptor. i think you will be very pleased with either quad. However, depending on the type of riding you do, you might wish to consider dropping the front sprocket on the quad. The 400EX comes stock with a 15-tooth front sprocket and I dropped my down to a 13-tooth for added low-end.
I would suggest, if you can swing it, getting the Raptor. The power and suspension is tough to beat for overall riding performance. This is just my opinion though!
