The 250EX will probably be a pretty nice atv. The suspension will not be good enough for you most likely though. From the pictures I've seen and the specs it looks like it has non-adjustable shocks (like the Recon). That means they have to work for the average rider. At your weight, you aren't probably the average rider, so it will still seem stiff.You might be better off to put works Performance shocks on Recon (or 250EX if you get it). They can set them up for your weight and they usually offer a much softer ride than stock. The weight difference on the 250EX is from the EX having aluminum rims and no racks.
