Ya, crazy racing!
Dakar competitor Lawrence Hacking lives in my town and I've done a few bits of composite work on his race truck.
A number of years ago, when he was still doing the Dakar on 2 wheels, I got to check out his ride close up and personal - wow, totally hand built bike, awesome fabrication skills of the guys who made the special bits.
Lawrence's riding skills are legendary as well and he wrote a book about his Dakar experience - a great read but don't know if it's still in print.
It would be neat to build a Dakar-themed street bike (adventure tourer?) but to do it right would be pretty expensive I think...
