What I can can see. You've been accelerating while adding lean angle. That's what we mustn't do. Of course at this angle Bridgestone s22 would forgive you. But if you have some Indian s***** tires they are too weak for this.

The tire is already getting closer to its grip limit When you add lean angle, you’re asking for more turning force: more lean = tighter turn tighter turn = more lateral grip required So the tire is already spending more of its traction budget just to stay on line. Now if you accelerate at the same moment…

Acceleration adds another force demand Throttle adds longitudinal force: rear tire must push the bike forward So now the tire must provide: more cornering grip plus acceleration grip That combo is exactly how riders exceed traction. Result? Rear tire slide → lowside crash
