To the OP: do you have sufficient medical insurance to cover your hospital visit should you get injured?? IF so, do what the hell you want.
Does anyone ride a motorcycle wearing just a business suit?? I see scooters here in London with the rider wearing just business attire (and helmet of some sort). To me, that looks more correct than the same attire on a motorcycle.
Stupid observation, I know. Guess I need to go grab a pint.
