I've always wondered how these guys don't fall over.  They tell me "it's physics, dummy!" but frankly that never really helped.  Anyway, you can try these death-defying turns yourself on the free PC demo for MotoGP 08, out now at playmotogp.com!

The demo lets you race the Mugello circuit, riding as either Spanish favorite Dani Pedrosa or American superstar Nicky Hayden. You can choose one of three bikes, and even customize the AI opponent to create an ideal challenge without getting blown out of the water. 

PS- if you don't hug on PCs, the demo will be out for PS3 and XBox 360 very soon as well.  If you're already sold, you can buy the full game here!
