I read the same article, and it's astounding how much throttle is used and how soon it's used as well.
Since reading ToTW and doing CSS level 1, the rolling on of the throttle once in a turn is probably the single most improtant thing I've applied to riding and you can feel the difference between doing it and not. But opening it hard, early, is very intimidating. I feel that improved body position will help improve my confidence by making me feel more comfortable, and it's also a psychological thing and let me focus on turning faster and getting on the gas harder, sooner.
Funny isn't it, that when we start riding on the track, and getting a bit quick on the road, lean angle and knee down is a thing to aim for, because it looks good and gives a perception of speed. Then we want to go quicker, and so less lean angle for less time at a given speed is what we want.
Roll on TA4
Out with an instructor early for me, and if by the end of the day I get 1:55's, I'll be happy as a pig in muck.
I'm always open to constructive criticism as well, so if you're out in the Inters and see me riding like a tw@t feel free to comment, but be gentle. I'm definitely the limiting factor not the bike, so time to tighten the nut behind the bars.
