Good thoughts Tim and I can't argue with most of them. I understand the concept of street riders not having the proficiency of those who ride repeated laps in a closed environment where learning is free of the dangers/ distractions on the street. However a few corrections from My POV and experience:
Emergency Braking: Emergency braking is the same as threshold braking/ track braking. When running race/ track laps, riders are pulling the lever as hard as they possible can on some corner entries. There is no more left to give...this is a rider's max braking force/ effort they will ever have. Period. They won't be able to build more pressure on the street. In fact, once a rider has squeezed their max in a braking zone, this is the max deceleration rate they'll experience. That is, unless they can slow a second traction source; the rear wheel. While this can be done with the rear brake, it isn't when in an emergency. Mainly, this is because use of the rear brake is rare and, will always be locked up, sending most bikes into tail wags, etc. If a bike has ABS, the rear brake will be mostly useless unless on a linked braking system. Linked systems are great on the street and pretty poor on the track in stock form (most). The problems stem from a lack of traction on the rear wheel due to the severe weight shift forward under max/ emergency braking. I'd bet many riders pull the rear wheel well off the ground in emergency situations (another reason a track environment provides superior skills training).
Again, the most important two things in an emergency situation for maximum deceleration is how the lever is squeezed and where the eyes are. It's really not about what effect the rear tire has on the engine or if a rider can control the rear brake at the same time they're hoping to preserve their life. The reason I asked the question of George about false neutrals is if one hasn't experienced one at speed on corner entry (even if straight up and down), they may not understand the difference of a rear end that provides friction (clutch out) and one that does not (clutch in). I'll take and let the engine help slow the bike in an emergency situation while pulling the front lever as hard and firm as I can muster. Additionally, rear wheel engine braking IS rear braking...and done all on it's own with no actions needed by the rider.
FWIW, we ended up here not by what I perceived as a beginning rider, but someone who asked how to stop more smoothly. Pulling the clutch to the bars is not that, IMO, and while George was speaking about emergency braking, I'm surprised this is an endorsed strategy for riders looking to increase their skills. Freewheeling a motorcycle to a stop is totally foreign to anyone who uses their brakes at the limit and aside from simplicity for newer riders, I don't understand the logic that it's a superior technique. As you know, in racing / track riding, we have plenty of unplanned heavy braking and line changes. Not looking ahead may result in more panic, but still, there's lots of dynamic changes that transpire several times a lap. I've got hours and hours of video on the ones I've caught.
Overall, track and street are different environments. Things we learn on the street will not help us progress on the track, however, skills we learn on the track will help us progress on the street when it comes to bike control and riding experience. Certainly there are survival skills learned on the street that will never be learned on any track...
YMMV
