A few years ago I discovered the joys of a well executed, steeply graded, down hill corner. They have since become my favourite type of corner, since they represent my biggest challenge, therefore giving me the largest sense of accomplishment when done correctly.
Down hill corners, the scariest of corners, presents sort of an intellectual quandry to me that's difficult to understand. At least it's difficult to make my wrist understand. My brain has the info, but it seems to defy the self preserving logic of my wrist.
I'm under the impression (from Keith Code) that the ideal weight distribution around a corner is 40/60. 40% front 60% rear. With this in mind, it's up to the rider to use throttle to control the weight distribution while cornering. If the throttle is just held constant, mid corner, the bike would actually drop speed. So to get the 40/60 one must then actively be rolling on the throttle throughout the corner.
While braking for the turn the geometry of the bike sharpens with the compressed front suspension, making the bike turn in quicker, but then you have more of a 80/20 distribution and risk running out of traction with the front. So roll on the throttle right? Sounds nice, but takes a steady hand since acceleration downhill on an m/c is not hard to do. Keep in mind we're going around that scariest of all corners.
My brain understands the concept, but my poor wrist doesn't want to agree, that acceleration through these corners will acctually increase traction, and the likelyhood of completing the turn.
In practice I find it to be a sound theory, and when done well the bike just feels super planted. But I'd like to hear other rider theories, thoughts or tricks they use for the down hill corner.
