Or perhaps they think their memorized street ride is going to directly translate to fast times at the track, but lack the technique to apply the skills to a new location

Track is a whole different world from street.
But making wrong decisions in either one can hurt.
So the key is learning how to make the the right decisions.
One is knowing the differences in riding technique between track, street.
Here are some:
The biggest is braking skills.
The second is steering input.
The third is being able to use the whole track surface.
The fourth is being blind behind you.
Another is understanding how a tire friction circle works. It's a simple concept that can help to make decisions when first starting to ride.
Simply stated is that a tire has x amount of traction. There are three forces that are placed on a tire, acceleration, deceleration, and turning.
When straight up on the gas.......all available traction of the tire is used for accelartion. When decelerating, all available traction of the tire is used for braking.
When steering and braking, the available traction of the tire is spit between turning and braking. T+B=Traction of tire.
When lean over and accelerating , the available traction of the tire is split between turning and accelarting. T+A=Traction of tire.
When a tires loses traction it is because one of the forces uses up more traction than the other.
So, you are going into a corner hot.......knowing that going in hot, using a lot of brakes, you have a good chance of using more traction for braking than turning. You exceed what traction there is for turning by being hard on the brakes.....lose the front.
Knowing this concept just might help you to make the right decision to stand it up, going off track, rather using up more traction than the tire has for braking or turning.
One of the reasons to get the bike stood up as soon as possible out of a turn is so the more of the tires traction can be used for accelartion and not turning.
Also, a myth is the bigger the contract patch the more grip....not true.
Also, hard braking does reduce the coefficient of friction of the tire somewhat....called tire load sensitively.

Understanding how the current track conditions affects traction is another.
Cold track, cold tires, the less tire traction there is for the three forces to use.
As the tire heats up, more traction becomes available from the tire.
If you did lose the front or rear.......knowing how the tire traction circle works can help you understand what went wrong and what needs to be changed in your riding.

I agree that its a great concept when first starting to ride. but its NOT a good track concept. its something that must be un-learned by the time u are in A-group... unless u want to crash a bunch while off the brakes.
heres a cool paper for u to read. check out page 14. I wish there was more research on tire load sensitivity on cambered motorcycle tires. but I can't find anything else.
