Poor judgement is bad all around. No doubt about that. Don't have buddies, ride solo - street or track.

I am still trying to get to the bottom of the tire spinning issue, and the more I think about it, the more I am convinced that the rider doesn't have to be in too high rpm. To be specific, I think for the Busa staying within 6k - 9k is just fine, and starting to spin the rear while being at 8k is as safe as starting to spin the rear being at 10k. And the correct way to do it is as I mentioned above - rolling it on smoothly, and simply stop rolling on when the rear breaks lose.

Just looked up TOTW 2 to see what Code has to say on the subject, and he actually advises to chose the tallest gear possible which will do the job of getting through the turn without redlining at the exit - it's common sense to avoid being forced into an upshift at the exit when you need to be hard on the gas. Let's say a rider enters a turn at 60 mph and reaches 80 mph on the exit close to redline of 11k - a reasonable example. A quick equation, and the engine speed at 60 mph should be 11k/80*60=8.25k. So, being around 8k is a reasonable thing to do. But there is no time to figure it all out when you ride, so a rider might chose a gear which at 60 mph at the entrance makes the engine turn let's say at 6.5k. Doing similar math, and at 80 mph on the exit, the engine would spin at 6.5k/60*80=8.7k - this is almost 9k rpm where Busa makes plenty of torque.

Based on the responses I am getting, I think there is a bit of confusion as what I am trying to figure out. I am less interested in what happens when a rider makes a mistake as opposed to what is the right way of doing something. I want to understand and comprehend the correct and logical way of doing something - from various angles, later on visualize it and practice in my mind - program the correct actions and reflexes in my mind - and only then go out and possibly try it.

I completely agree that if a rider wants to catch his buddy and opens the throttle abruptly at the exit causing the rear to spin, the higher rpm may save the rider if the rev limiter kicks in, thus covering for his mistake. And if such rider was in pretty low rpm at the entrance, let's say 4k, he will be tempted to go WOT and maybe for a moment he will be OK, but when the torque kicks in and the rear breaks lose, there isn't much that can be done to save it - he overstepped the traction by a huge margin.

I however would not use a rev limiter as my standard technique to control the spin, but rather lely on smoothness of my throttle hand to assure that the rear tire overstepped the traction threshold by 1% and not by 50%.

Code made an interesting point. Another way to get out (or take advantage) of the spinning rear is to start straightening the bike by turning the front slightly to the inside of the turn - pretty much how one would normally start straightening the bike. The bike being more upright will cause the rear to hook up quicker. Actually, as I typed this I realized that since we are talking about exiting the turn this is being done by the rider anyway. But, if in the middle of a turn and the rear broke lose, slightly straightening the bike while holding the throttle steady would do the trick.

The whole spinning the rear thing is done by exceeding the limits of traction by a small margin. That's the key!

EDIT: while I was typing my response, Mr Bogus was typing his... Not sure how lap times got into this as I don't really care for lap times. I ride on the track and street about the same, except it's less of everything on the street. So, the point is I am SIMPLY ENJOYING AN AGGRESSIVE RIDING, and getting in the zone to maximize the pleasure and joy of riding is the objective of this entire exercise, at least to me. That is why I don't have to squeese every pony out of this bike and stay in the highest rpm possible. It still happens occasionally, and I get close to redline now and then.
