that whole real road racing series is awesome. i like moto GP too but these guys on streets have even bigger balls. both wheels off the ground at those speeds is crazy
the last one i remember watching was the Cookstown 100. that was a few years ago it seems.The Isle of Man guy's do have balls of steel there's no doubt about it...
If you like the TT check out the North West 200 it's also bikes racing on winding country roads in Ireland.
