To add my 5 cents to the debate... I think Despres is a gar superior rider. I don't ever remember Coma beating him or finishing near him unless Despres had a mechanical problem or other setback (police directing him onto wrong road, etc). Coma tarnished his image somewhat at this year's Dakar with his cheating and he isn't overly well liked by the other riders. You'd be hard-pressed to find anyone who doesn't think Despres is a great guy. I suspect if KTM had to choose between them Despres would have much more value to them. Coma is a gifted rider, I'm not knocking him at all. I just think Despres brings alot more to the table.
