Check this out:

Brian Kinney is a T1 paraplegic who's figured out a way to get back on his Kawasaki Ninja 650R. I never thought it was possible to balance a motorcycle on two wheels if you couldn't move your legs, but apparently that's not true...

As long as you have landing gear installed on your bike (to save your butt when you come to a stop since, you know, your legs don't work) you're good to go. Dude!

While I'd never do this myself in a million years, I think it's very badass he's putting himself right out there on the same bike that broke his back.

You can view the video he made explaining how is bike works here: http://www.spinalpedia.com/blog/2012...-rocket-rider/
