Their best PR is him riding the bike and winning on it at the TT which is fast getting world wide audiences thanks to technology. He`s a maverick but that`s what makes him what he his. Uncle  Joey was the same so it`s a Dunlop thing. I like him and I think the majority do.
He`s not going to change so they need to use him as he is. Whatever bike he rides he will win ( providing the bike is up to it) and queues will be forming around the world to buy them.
What problems has he been causing other than the jacket??
