Swapping to 190/55 rear

As the title suggests, I want to know if the upgrade is worth it in the future. I am currently running Pirelli Diablo Corsa 4s in the standard 180 size and I am thinking of getting 190 Supercorsas for track due to recent suggestions. Currently only riding on the street and I am planning to do track days soon. I've heard that upgrade to 190/55 or 190/60 would be better for handling, I am unsure if that is true, thus the question. Why would R9 be factory 180 if 190 improves the handling? Thanks!

Hello again everyone! I've heard a lot of praise and recommendations regarding 2wdw Ecu flashing and general tuning. Unfortunately no reputable tuner except BT moto will work with clients outside of NA. I've heard a lot of great things about them, even more so with their works on Euro bikes. Has anyone tried them with Yamaha or specifically with R9? If so what do you think? I am planning to work with them for my R9, just ECU flash and air filter mod since aftermarket exhaust isn't legal where I'm from 🥲🥲 Thanks! 🙏
