Did you read this sticky? https://www.gixxer.com/forums/44-trac...ing-track.html
My first track day was last year and needless to say, it was full of mixed emotions. It's a HUGE learning experience. However, you may be disappointed to hear that your first 1-2 track days should be relatively slow. First, learn your lines. Then start incorporating body positioning. If you search through some of the older threads, you'll find Anthony D giving out that very same advice. After you get those two down, speed will come with saddle time. Also, go at your own pace. The moment you start trying to keep up with faster riders, although it may be temping at times, is when you could easily be pulled out of your skill level and down into the earth shortly after.
If there are instructors out there at your disposal like I had, take advantage of it. Every session I would trail an instructor who would show me lines and examples of BP and then he would follow me and provide feedback afterwards. This progress much easier and much faster. Actually, the head instructor followed most of us throughout the day and played the film for us to watch in between sessions. Here are some things I like to bring with me -
1. Water and gatorade - lots of it
2. Healthy snacks
3. A pop up tent/cover, if you have one
4. A fan, if you have a way to power it
5. A set of tools, tire pressure gauge, air compressor, extra motor oil
Make sure you do all of your prepping tonight so that way you can get out on the track first thing. Clean/lube your chain, check oil and brake fluid levels, etc... Go out, have a good time, learn, and meet people. I have met so many riders who are willing to help others out, regardless of experience.
Be sure to post about your time out there
