Happened to me more than once on public road. Luckily every time God save me and kept me upright. When this happens I up-shift just to be sure, but another thing I realize if a chain is on tighter side than It has tendency to happen more often. Chain on my Ninja should be between 20-30mm of slack and I realize when I keep him between 25-30 mm it is much better.
I don't know which group you were riding with, but there is a big difference between your speed and most riders. Towards the end, it looks like you put chasing the other rider as more of a priority rather than making sure you give enough space to other riders. at 5:29 white leather rider was carefully passing the slower rider and you went to his line. It could've caused a chain reaction. "Restraint" is important for everyones safety at a regular track day.
Ridesmart has 4 levels, this weekend they combined the top 2, there is always a big difference in speed with a “fast group” track day rider and racer. To be honest I’ve had more close calls trying to pass someone slower. The roll speed is so different that usually I’m gone before they even have a chance to realize I’m coming up.
