Always a bit risky to put a guy from 4 wheels to 2 wheels.
Michael Schumacher tried it and crashed.
I think they are used that they can go to the limit of the car.
If they reach the limit or go over it they can feel it as the car starts sliding to the side, nothing else happens.
Thats why they are very fast when they try it the first time.
On a bike without electronics this will end in the gravel within the first fast lap.
Maybe the electronics/datalogging pointed out that he should go a bit slower because he is over the limit and the little electronic helpers are preventing him from a crash every second corner.
By the way, Michael Schumacher was 2008 on my favourite track (Pannoniaring).
He was only 3sec faster than me
Ok... it was the first day for him on the bike on this track
But his bike was a well modified modern bike against my old close to stock R1.
