Ok I'm going to wade into this with some insight .......... and it kinda goes back to the whole peaceful, well thought out and presented, totally un-emotional (
) discussion I had with Ereb. about backing it in.
I didn't realize fully that the technique Stoner was using is perhaps idiosyncratic to his background in Aus. dirt track, and is in fact pretty alien to many outside that code. I can in short now see
a. why it seemed alien to Ereb. to accept that this is may be used to back it in and maintain speed, and
b. why I found it alien that he could not accept it.
Owing to the manner in which, instead of rear brake, the throttle is used to break traction ( hence spinup the rear faster ) there is a propensity for the front wheel to come off the ground. Even though traction is broken the spinup does provide a large forward acceleration force in the direction the rear wheel is pointed, and the mass of the bike likewise will try and lift around the rear axle, just like any wheelie.
So in the picture, even though it is difficult to see conclusively, I would suggest that it is very likely the case. Also I think the amount of daylight we see on the ground under where the front wheel is would suggest that the front is is at least "light".
Be patient and we may see a photo from on front one day were it is more obvious.
Because its on tarmac it will never be as dramatic as this:
( yes I know its speedway but its the nearest thing to Aus. short circuit/dirt track )
more like this:
but its essentially the same.
But I would also proffer that Stoner seems to be using weight shift and lean angle well too, not just throttle, to achieve the same end. Its kinda why I feel he is a greater proponent of it than McCoy was. Stoner gets more speed out of it. And its kinda spooky the lean angle he does it at
