Marc Marquez, MotoGP's resident wild-eyed, ever smiling sociopath just upped the adrenaline levels in the Austrian Alps. 

Aboard his rabid Number 93 Repsol Honda RC213V, fitted with 483 huge custom tire spikes, Marquez attacked the most demanding slope on the alpine skiing World Cup circuit-- the legendary Hahnenkamm piste in Kitzbühel.

"It was really difficult to keep the bike under control, but I’m young and it’s good fun to try some crazy things! We enjoyed it and we could see after a few runs everything that was possible," said Marquez.

“The piste was really well prepared. I could really get going and I had a great feeling out there. The grip was unbelievable, even for a wheelie!”

The event was put on by Red Bull--which sponsors both Marquez and the Repsol Honda MotoGP team-- just a year after sending Max Verstappen up the same hill in a Formula 1 car.
