protect youself? 
  having a chat last week about leathers etc and if/when not to wear them (on bike nowhere else:P).  Qusetion:  why does it seem to be acceptable to some that you can wear jeans, boots and leather jacket on a 'classic' but not on a sports bike?  Does it hurt less if you fall off?
 
 Personally, I think gloves, boots and jacket are essential, but after that wear whatever you feel comfy in (except shorts!!)
