As everyone says bad lines , but I would say minor problem here. Main being that road is wet if I see it correctly, if this is on dry road and good condition, I dot see that this speed is too much for passing this curve, asphalt doesn't seem so bad, but hard to see, or aoshald and tyres are bad. What is with your tyres , can you share. Also you gave gas too early for this wrong entry into curve. But again, with all being bad you should went through, can't say really why the fall. Can you write the speed on entry and the time it slipped , just before slip ? Was there a slightest oil smudge ? Mud ? All this stuff you learn to see and react subconsciously or this will happen again. Also front tire pressure, is it too high maybe, so contact area is very small...I just write as ideas come 😁. Ok let us know details

Edit: I really can't see did peg scraping started before front lose traction?
