Ant Meo on the 250 4T http://www.motoverte.com/site/fabien-planet-remporte-the-race-47098.html#images
Keep an eye on the US team, ZipTy racing they are doing R&D with different linkage rates as well. Also they are experimenting with taller chain sliders to equalize the chain torque effect on the suspension. Hope ZipTy will have some of these different set ups in the near future.
Things that make you go hummm. Y porque? (that's spanglish for "why") I'm thinking the only thing they could be covering up would be FI? Or is it some newfangled lower emission 2 stroke?
there was snow there, i am thinking to keep the works (carb) from icing up. Good call, There is word that TM is prototyping FI on their 2T s so that is a good logic too, to keep it under literally under wraps for now.
