Things get really fast at 1:10 ;-)
When I was at Cartagena for Bike Promotion Track Days I had Simon Crafar as personal instructor. One day we realized Ana Carrasco was on track as well doing some pre-season testing and Simon went after her. Fortunately, he had my camera on his bike. Needless to say, with a former 500cc Grand Prix race-winner and an ex Moto3 racer, the footage is pretty epic, especially the second part.
Evidently, Ana was trying out a Moto2 kit bike, probably for a local or European championship. Check out the sound of that thing when Simon closes in on her. She also does some nice back-wheel-in-the-air braking at the end of the main straight (again 1:10). Enjoy! :-D
