My theory is that all the winners have been World or National Enduro champions in the past .
Years of enduro at the top level seems to be the recipe for good rally riders , All have exceptional skills and a natural ability to read unseen ground very quickly.
I think ,Gaston Rahier was the only MX world champion to win the Dakar ,not sure what offroad /enduro experience he had !.
As years go by ,KTM now have so much experience they can teach the art of Rally racing ,although there don't seem to be too many younger guys coming through for KTM,
The 2 top guys have their ever faithful water carriers ,but don't seem to have anyone who will take over the reins.
Maybe Coma and Despres plan to be around a while longer yet, i hope so.
Or maybe KTM are hoping Johhny Aubert and Taddy Bluzasiak will be the new guys to come through,both exceptional riders and already in the KTM system.
