Besides proper riding gear, there are other requirements and tips that will help ensure you and your bike are both ready and prepared to make the most of your first track day. Every track will have its own requirements and conditions, so be sure to confirm with your local track before heading out.
Most modern motorcycles have an interlock system built in to prevent you from riding off if the kickstand is down. For whatever reason, riders like to disable these. Maybe it’s because as soon as you click into gear, the bike kills itself and, (I’ve done this myself) it can be kinda embarrassing.
