Finally, a site where I can see real goodness...
I have plans of my own, to build a F3 racebike. I am buying a KX500 engine at the moment (96) and have a NSR250 MC18 chassis already lined up.
I race an Aprilia RS250, so I'm using the suspension and fairings off that, possibly the swingarm as well, if I can't modify the linkages to match up with the shock.
