I use the rear brake all the time, but for stability, and very light applications. Maybe 10-15% of what it has to offer. If you replace our stock pads, with vesrah, you can feel it enough to be able to use it. In stock form, forget it. It's an on/off switch.
Really, that's about it for the turns, too, and the front. Enough to be able to feel the fork compress, and enough to feel the road, through the tire. Not for some amazing speed advantage. I played with this, on Monday. First trip of the year up the local canyon. Without some front brake, the bike felt like the old 83 Honda v45 magna. The magna was an amazing engine, in this strange chopper frame.
I like reading about specifics, and how you guys do it because I'm going to remember and try every technique mentioned.
