First Bike what is essential that should get done or I should purchase

Recently started riding and purchased a 09 Yamaha FZ6R. I’m just wondering what are some good things I should look into doing maintenance wise and what are some essential must-haves I should look at getting. I’ve purchased some gear, a quadlock with wired charger, and I plan on doing an Oil change this weekend. Also purchased a CS Racing Full Exhaust system. It has about 16k miles. And I just took it on a trip to Chicago. I did lube and clean up my chain and I did have to also tighten it.
