I've twice mentioned the 2012 Isle of Man TT motorcycle race in recent months. It's probably the world's premier event of its kind - not to mention probably the most dangerous motorcycle race in existence, as this 2005 article makes clear.
I just came across this video clip of the 2009 race, showing what happens to motorcycles as they negotiate some of the most tricky parts of the course. It's in very slow motion, so you can see details as small as the deformations in the tires as they come down after a jump, or the impact of a rider's knee on the tarmac as it sends ripples up his leg. I strongly suggest watching it in full-screen mode.
As a commenter said about the video, it 'captures the true essence of the [race]'. I think so too - and also its danger! Remember that you're not watching motorcycles on a purpose-built racing circuit, but on regular, narrow streets. They're re-paved before the race each year, but as the close-up shots make clear, that doesn't remove all the bumps. Hazardous indeed!
