Yamaha, always. Anything else is like switching football team allegiance - i just don't get it.
I think Vinales will be one to watch this season. Rossi will always be, well, the legend Valentino Rossi #46!
I think Lorenzo will do well on the Ducati because he is such a good rider, but he's let his heart rule his head by leaving Yamaha. He wound me up a few times last season when you could tell he wasn't trying - something was going on in the background. Maybe the Ducati talks?
