Sliding in racing isn't showboating by any means.

On any given turn you have two things to do that determine how fast you can travel around the corner - get from the start of the turn to the end, and get the bike rotated from the starting angle to the ending angle. Depending on the configuration of the turn, the latter may be the rate determination, in which case sliding on the way in or the way out makes you quicker.

I'm no Casey Stoner, but used to race regional CCS / WERA and AMA Pro Thunder, and it was a technique we used all the time, Bang too many downshifts into the slipper clutch under braking, push the back end out, stick it in the middle then roll off the edge of the tyre and light it up coming out.

Did the same racing cars, though my Spec Miata didn't quite have the power for the big exit.

That's pretty much irrelevant to what we are talking about. As weight comes off the tire, contact patch gets smaller. The relative length & width of a contact patch of any particular size does have technical ramifications but that's not what is relevant here.

Noobs in either cars or bikes are told to brake in a straight line and then turn in because it is easier for them to handle one thing at a time. But if you don't get all the braking done before the corner, you can carry more speed farther in. If you are doing all your braking before the corner, I will pass you while you are braking because I start braking later and then brake deeper into the corner. To trail brake you "just" have to complete some of your braking while you are already turning, which is more difficult to maintain control doing, but is faster.

The concept is g-force or friction circle. Using accelerometers you can graph the g-forces on the bike under braking, acceleration, or cornering. If you brake first you get a spike toward the front from the heavy decel. Then the data point comes back toward center and then it goes to the side from cornering force. The idea is that to maximize use of the available traction, you seek a more "round" graph.

Yes the graph plot is forward under decel, but rather than stopping decel and THEN starting to turn, you transition into turning as you ease off the braking. The plot swings from heavy braking and no turning, to moderate braking and slight turning, to moderate turning and slight braking, into no braking and all turning. Like powering out in mirror image.

You don't wait to finish turning before you start accelerating. But (without traction control) you don't necessarily crank max throttle in while you are still leaned waaaaay over. Same concept on the other end with trail braking.

Well this all makes sense, I just don't understand why twist of the wrist II disagrees with it. Is that book really for "noobs"? It makes sense that if you still have some longitudinal acceleration either forward or back you should use it of course to maximize your speed, so logically what you're saying makes sense and what I always thought as well, but it seemed like TOTW2 disagreed with that, maybe it doesn't.

We were up there on the 19th and it was crowded and loud. An HD Rider decided he was going to announce his departure with lots of noise. Made sure everyone was looking his way as he rode off towards 28N with his beanie helmet riding on the sissy bar. He hit the first bump and while the helmet bounced down the road he roared off down the hill only to come slinking back a minute later to reclaim his lost brain bucket. Everyone was roaring with laughter. It was priceless.
