Yes, i can see that, but surely if it was 'natural talent' there would be some guys who get into bikes into their early twenties say, discover they have this 'natural talent' and take the world by storm. But it isn't like that, it always seems to be the guys who have grown up with it.
As Casey Stoner said 'I was always poor on the brakes and spent a lot of hours in practice to improve, now i'm very confident on the brakes'
So it wasn't his talent that made him improve but hard work, persistence and practice.
We could probably go round in circles with this but still, it keeps the grey matter working
