I have read quite a bit, studied, been riding on and off for over 30 years. Got back into riding pretty extensively about 4 years ago after being pretty "intermittent" for a couple decades. Anyway, since getting "back into it", I've studied quite a bit, and have worked hard to get better at "trail-braking", among other things. Seems pretty natural. In the dirt especially, knowing how and when to brake, even when turning, seems pretty critical. A couple weeks ago I took my first "formal" riding class, the "Idaho Star" experienced course. They focus heavily on braking before the turn and being back on the power before starting the roll in. They also focus on straightening the bike up before emergency braking. All counter to "trailbraking". Does MSF teach the same thing? I expect that these are all aimed at the new rider to avoid overloading the contact patch.
