guess thats why we have aftermarket parts available to us street folks. I think i posted on one of the topics about an '06 R1 I saw at dynotunemotorsports pull a 168 at the rear wheel. Owner said he had a milled head and a full Arrow exhaust which i saw. I would hate the day when it came that we couldnt add things to our bikes to make them faster. To me thats half the fun.
