From the little I read Rossi was the one testing various new parts and Maverick was left to get on with acclimatising to his new bike.
all i know is i can't wait for it to start ! going to be a great season. Rossi will win one or two and be consistent podium finisher but think title will be Marc/Vinales with a sprinkling of lorenzo , cal and ever the dreamer a victory in the rain for Sam!
