The rider in this video wasn't even a minute into the Deutschen Rundstrecken Challenge at Hockenheim when he was nearly decapitated by an errant bike.

The teeth-clenching close call was captured from behind the windscreen of the rider, who was doing about 120mph when he saw the accident and started to brake.

When the bike grazed past him he was still doing 70mph.

But in a fit of unbelievable heroicness, instead of slowly pulling over so he can change his underpants – which is what we would have done – the stoic racer almost instantly accelerates away.

Watch it below. It's the most harrowing thing we've seen through a bike windscreen since this cracking video.
