This may vary slightly from the topic, but what 120/70/12 tire has the highest gripping compound for wet or dry conditions? life span is not a concern as my front tire has very little weight on it and seems to last about 5-6 times as long as the rear.
To add to the topic, the knowledge of theoretic optimal technique for any skill never seems to be equaled by the level of practical understanding. Once we obtain the knowledge through study experimentation etc, true understanding(in the context of braking) as klaviator stated takes time and practice. Even the best riders(who's skills are beyond what I could ever dream of attaining) fall short of mechanical perfection. I believe all of us have room for improvement, but at some point near the limits improvement cannot be gained without reaching the limit which is not possible on streets and is therefore irrelevant to us normal scooter riders. I do agree that a very low percentage of riders have a thorough base knowledge or understanding of proper brake use. I will have logged over 20,000 2 wheel miles at the end of the month and although I have studied the theories of frictional values and mass vectors for several years I am now just beginning to see how little actual practical understanding I have.
I am looking forward to many more years of riding and hopefully learning along the way to become a better and safer rider.
