I actually spent some time on this topic last year. I personally have been using the rear brake for years on tracks, just a split second push just before the front brakes are put into use. It really does help with front end dive and tail wag in heavy braking zones. The thing is I was reading an article about how to use the rear brake in corners to tighten a line? There is some truth to it, not sure if this is because of affects on suspension, or it really just slows you down, but it does work fairly well? Problem is, if you have a SR #1 while using the rear brake, you had better get off the peddle before you roll off the throttle!! It gets sketchy very quickly!! (not that I would know, LOL)
I ride a V twin 1000, so SR 1 is a biggie to me, I can push the front end out if I go anything past neutral throttle at almost any speed in 1st or 2nd gears. I did try to learn it some, but is was too distracting to be of major benefit to my riding? It also has a bit of clash with throttle roll on out of corners? It took to much timing for me to use, but if I remember correctly, Fredie Spencer smoked his rear brake every race because that is how he controlled the power of the 500cc two strokes of the day? He knew when the tire would light up, and drag the brake to control drive in and out of corners? Not sure this is useful, but stuff I have tried?
