Ref the new tyres bit... I once had a bike in for its annual test, and the place were a bike tyre specialist too. It was a greasy winter day, and they were just finishing off replacing the tyres on a Triumph Sprint ST. I heard the proprietor say to the guy to go very gently for at least 50 miles after he had paid and was about to leave.
Five minutes later same Sprint ST was back with busted plastic, having given it too much wellie about 200 yards away...He tried to blame the tyre fitting...
