Took the new GSXR to Thunderhill for a track day on Friday. Bike was absolutely mint and dialed. I started in C group as it was my first track day, which was terrifying. 160mph at the end of the straight with other people going about 80 and no idea what line they plan on taking. Thankfully after an instructor followed me for a few laps they moved me to B group which was much better. Here's a video from the moving chicane class. Only clear lap was out of the pit, after that there was a lot of cruising around trying to get around people.
