Trev,
What helmet size (snigger, snigger) are you? I have an old (but proper - white with black visor) Bandit that's surplus to requirements if you still want one. I need to warn you that despite having specific sizes (in inches) marked on them have very variable fits. I tried on three of the so-called same size before I found one that fitted.
As FBF mentioned, they aren't the quietest of lids and it's a real shock to the eyeballs the first time you go out and hit 100km/h, but a draft excluder strategically applied to the upper part of the visor solves this, and the dark visor is so dark, you can't see the draft excluder from the outside.
I originally bought mine when I lived in Holland and had a streefightered Kwak Z1R - the helmet goes well with this type of bike, although I switched to a Kraft when I had my Speed Triple. To be honest, the Kraft is a much better (and cheaper) helmet, even if it doesn't have the same street cred as a Simpson.
