Re: IQ drop   
 THAT's the reason I don't have one of those bikes.  I rode during high school, but then did the got married thing and bikes went away. September will be 3 years I've been back riding and I would absolutely love to have a fast "street" bike.  The problem with that would be, if I had it, I would ride it...and I have never been able to do anything just a little bit.  I have too many other things I want to do before leaving here to own one of those, and risk the results of my IQ drop should I get on it.
