Ok, this isn't strictly motorcycle related. But it is racing related, and motorcycles do run this race. :-)
This is an onboard view of a friend and co-worker as he does the climb this year. He came in 2nd in his class. It's pretty interesting to watch how the landscape changes as he gets higher.

 

Man oh man if only one day I could get to even ride that road up the hill, don`t mind if it`s not a race. Have watched some videos from the olden days of Volvo 240:s with closer to 800hp doing the climb, a bit like strapping an Ariane class rocket boosters to a coffin on a shopping cart...

 

Yea, when you realize there are no safety rails on most of it and the cliffs are hundreds of feet down, just to hit rocks, it raises the pucker factor a bit.

 

As seen here

 

Woah...

 

Yea, in that video, they were actually done with the run and everybody was just coming down off the mountain. You'd think if you had a bike you were racing up the mountain, you'd take it easy on the way down.
But not only did the guy have to deal with a bike falling from the sky, he had cliff on his right side to deal with.
