You say "Weighting hands - YCRS advocates this, CSS advocates none at all."
None at all is unrealistic. We aim to reduce any extra pressure on the bars under braking but realistically speaking there will still be some pressure transferred forward and some pressure on the bars. Our goal is to use the tank and our legs gripping the tank to anchor our lower body so that the pressure on the arms/hands is reduced as much as possible. Here is a quote from Twist of the Wrist II that explains this.
"Weight transfers on the bike are an obvious source of traction reduction, as we have seen in the throttle control chapters. But this business of holding on has a huge effect on traction as well. There are a number of ways to minimize this effect, once you understand it. Braking is a good example because most riders go pretty stiff when they get on the brakes and thus transfer more weight onto the front than is needed. Taking some of the weight off braking-deceleration against the tank lessens the amount of weight on the bars and the result is: 1) You have the rear wheel on the ground (in really heavy braking) a little longer: and 2) in less-than- all-out-braking the front end has more travel to work with the pavement ripples, maintaining better stability and traction.
Stiff Corners: After braking, some riders stay stiff-armed on the bars; the upper body is driven forward by a deceleration force of about 0.2 to 0.3 G leaving extra weight on the front-end of the bike. Potentially, up to 100 pounds of weight is transferred tot he front end when that weight could be on the seat or tank, 24-36 inches further back. Forgetting to relax is all this really is."KC
