This on-board lap of the Nurburgring Nordschleife on a home-built Yamaha R1 with precious little in the way of electronic rider aids - traction control and ABS - in the pouring rain is properly scary. Yes, it's running on full race wet tyres but with all that standing water, the rider is either brave or foolish. And he's not hanging around.

Wet - And Fast - Lap of the Nurburgring Almost Too Hard To Watch

The Nordscheife circuit at the Nurburgring is one of the most fearsome track experiences you can have on a motorcycle (or in a car, for that matter). 14 miles, 154 corners, blind brows, sharp dips, banked turns, flat out straights, it's got everything and all with virtually no run-off areas: just lots of Armco on either side to make sure you come to a quick stop when you crash.

In the dry it's awesome but, in the wet, it's simply terrifying. In this part of Germany, it doesn't just rain, but it pours and the amazing thing is that they still let people pay the fee and head out onto the track. It's madness! Brilliant, but madness!

This guy obviously knows his way around the circuit and the home-built Yamaha R1 is at least running on full wet race tyres, but with all that standing water, not to mention a visor that is probably misting up and water leaking into his leathers, it's an incredible piece of riding.

Throughout the lap, he is deliberately avoiding the dry-lap racing line and sticking to the outside of each turn which, ironically, offers more grip in the wet.

Hats off to the rider.
