That technique IMHO is rarely justified for the majority of routine street riding being done. (repeated speed runs up and down the canyon isn't routine) Hanging it out there probably increases risk in more cases than not. This is due more to the myriad variables found on the street that aren't found on the track where this technique is used to eek out the last bit of performance of man/machine/surface in a tightly controlled environment.
As for the technique you shared, the weight of either knee moving outward six inches or so is insignificant in relationship to the overall mass of my 500 lb. bike with my 250 lb. carcass on it. On a "big heavy BMW touring bike" it would be even less significant.
If you are doing this as part of shifting weight to the ball of your foot on that peg, then sure, every little bit helps and all. Do you feel this is something a rider having problems turning should focus on first in order to improve their technique?
Would this take priority over practicing a simple weave using the handlebars to increase familiarity with steering inputs?
IMHO what you describe is only helpful as an advanced technique after having mastered the foundational skills. The ones lacking that caused the rider to miss the turn to begin with. Braking, calculating the line, steering the bike, looking through the turn all have to become a practiced skill before adding anything else to fine tune technique with subtleties.
Taking the main points in you post in order.
Go back and read my posts, nowhere did I say hang out the side like Marc Marquez. As radical as I got in my make believe demonstration was a 2 inch shift on your seat, dropped shoulder, weight forward, and knee out. And I said find you own comfortable limits. If that's MM style well all power to you, if its just a slight lean to the inside, it'll still be better than sitting bolt upright 1950's style.
Routine street riding - the topic being discussed was a guy who lost it on a country road at 60 mph, an a large BMW tourer. The OP felt the corner could be taken at a speed significantly faster (70/80mph ???), up to the point of dragging pegs. The topic never was beginner commuter riding or variations that people want to chuck in.
Myriad of variables on the street - I'm repeating myself. That's the very reason its even more important to develop a riding habit of always being in the best position to control the motorcycle. On a track you just doing it for speed, on a country twistie, it may be your life. Anyone who says they've never misjudged a corner is either full of BS, or rides like a granny.
Hang you knee - I just gave that as an example how little or how far one can apply the technique of weight shifting. I'm obviously quite interested in the topic so looked up a lot of old footage to see just who and when the classic 'tuck' racing position changed. The earliest footage (all on the internet) of a change in style that I could find is of Gicaomo Agistine (late 1960, early 70) who is the first to just hang out a knee. Think about this, the perhaps greatest motorcycle rider of all time rode classic style, but did hang a knee. If it worked for Gicaomo does anyone really want to say not worth doing?
Fundamental skills - Why does everyone assume the rider who didn't take the corner was a beginner? Didn't make a turn, must be a beginner. Not a very solid reason. By the choice of bike I'm actually assuming he wasn't. Could be a whole lot of reasons why he didn't make the corner, even the choice of bike being one of them.
