In a nutshell.....
Personally, I don't think you need the full 12" or so of travel from a MX bike, so SuMo bikes get lowered a little. You're not doing stadium triples on it. The MX suspension is setup to handle small bumps, ripples if you will, with ease, then progressively stiffen the further up the travel it gets.
The SuMo suspension is setup to more closely resemble a roadrace setting, with the ability to land a jump without knocking your teeth out. It is basically stiffened, with new rates of comp. and rebound installed. I think the rate of suspension travel is more linear with SuMo, more progressive with MX.
