First upgrades for a track 2018 track 390?

Hello fellow trackway enthusiasts. I'm getting more serious about doing trackdays and want to pick up an RC390. As I haven't been able to find a used one in my area, I'm looking at getting one new and getting it setup.Having never modded a bike for track usage, what should be my top say 5 upgrades before hitting the track, or is it really "ready to race" out of the box? via /r/Trackdays https://www.reddit.com/r/Trackdays/comments/cl0249/first_upgrades_for_a_track_2018_track_390/?utm_source=ifttt
