Pirelli states they are designed for a 6” wide rim. And the GSXR 1000 has a 6” wide rear rim. So, it’s honestly a perfect fit, with no deformation. The tire is just much taller than a 190/50/17, so it comes close to that plastic fender is all. Now, if someone tried to fit this on a 600/750 with a 5.5” rim, I could see what you mean by that.
The 200/60/17 tire is just a tiny bit shy of 2” inches taller that a stock 190/50/17 tire.
