This is such a missed marketing opportunity.
If I were with Joe Rocket, Alpinestars, Teknic, Dainese, or any other brand, I'd FedEx him a complete set of riding gear and ask him to wear it so that he's safe on the road. If I were Keith Code I'd totally offer him a free run in the California Superbike School and use the free publicity for the school.
I don't hate the guy, although I think he's a spoiled brat at the moment. (Which would be difficult to avoid if someone made you famous at 16, in fairness.) The guy can do what he wants, but I'd feel better if he were in leathers so to project an image of safer motorcycling.
