lets see, spent a couple years on an FZR600, a couple years on a 99 R1, then a couple years on an aprilia. Spent time on brainerd international with the aprilia for a few seasons, I'd say I've ridden a fair bit.
well, a PROFESSIONAL rider can get high 9's out of a hayabusa, an amateur might get into the 13's if he's lucky. If you really want to, search around. there are plenty o vids of a few supras outrunning bikes on the freeway. Are you likely to run into a street car that can outrun a bike...
In a straight line, of course. cars have twice the contact patch that bikes do and can indeed corner at higher speeds. see the test of the gixxer 1k vs the corvette in last year's motorcyclist for evidence.
