I really hate to be the 'devil's guy' here Medic cause I'm completely on your side but it prolly would just be a waste of money getting a lawyer. There are no damages to go after and no tangible harm was done.
You might get further by contacting customer service at Yamaha Corp. or something like that. Just a thought.
I'd look into your local Joy riding and unlawful use of a vehicle laws. Up here when your told not to drive the vehicle, and you can't provide proof that you absolutly needed to drive said vehicle. That is joy riding.
Might give you some extra leverage when dealing with the bike shop manager.
This gives me visions of the two blokes in Farris Bueller's day off when they took the Ferarri.
