I tried it once. Brake-Throttle-Turn. There’s a loop (or used to be) near me called “Harry S” (Truman Drive) a couple of long sweeping right turns, banked a little -a good place on the street to get the knee down.
I found it could be a useful technique.
I abandoned it when it betrayed me on the final left turn at home that day after many laps on Harry S- I lost the front trailing the brakes off (something slippery? - I felt it go- almost in slow motion) and broke my foot peg and a small foot bone.
I found that the technique wasn’t at fault, my timing and application of it was, but it as a trained reaction contributed to the inability to recover after I felt the front bite again when the brakes released and the wheel roll. I needed that tire to press on the pavement and when the throttle was applied there wasn’t enough front traction to keep the rubber side down.
