Picked up this baby. Thoughts?

Hey everyone! I just recently Bought a 2003 CBR600rr on Facebook marketplace for 4 grand. It has 23k miles on it. A GPR stabilizer, power commander system, upgraded front brake calipers and also a yoshimira exhast. And from what I heard upgraded headlights. What are your guys thoughts? The only thing I have had to get for it was a new side mirror and new back tire and it was set. What are your guys thoughts on it? Was it a steal or did I over pay. I’m coming from a Ninja 250 so it’s definitely big upgrade can’t wait to ride with y’all!
