Yamaha is also referring to the Bridgestone 501 & 502 that come stock from the factory. (says so right there beside the tire pressure recommendations) Most riders will go with a better grade of tire when they change tires. Tires are like a box of chocolates. I like Michelin Road Pilots and running 33psi in in the front will destroy the tire. I posted earlier that IMO 33psi was too low for a street tire and you replied with a SAD emoji. I guess you don't like anyone else having an opinion. It's fine to trust what Yamaha says, but you need to remember that the engineers that wrote the owners manual are the same engineers that used the wrong gauge wire on the early headlight harness's, they designed a clutch basket that liked to rattle vibrate and explode, a cam chain tensioner that would slip and let the engine grenade and a main wire harness that had to be recalled. Trust your manual and Yamaha engineers all you want, but remember that others have opinions and experiences too.

My S10 came with Bridgestone A41s from the factory, I ran them at Yamaha’s recommended pressures and the front was fine, no cupping, no uneven wear and they weren’t destroyed. After the A41s were finished at around 8000-9000 miles, I replaced them with Michelin PR5s run at Yamahas recommended pressures, the result was the same as the Bridgestones, even wear and the tyres weren’t destroyed. The results were the same for the following sets of PR5s. I probably replaced the fronts early, but I prefer to fit tyres as pairs. I have recently fitted Continental TA3s and these also look promising.
I have nothing at all against you or anyone else having an opinion, although you obviously don’t like anyone disagreeing with you. Mind you, when you list all of the faults that Yamaha engineers apparently built into these bikes, it does make me wonder who the heck bought this POS that we all ride around on in the first place and just how long it will be before they all self-destruct.Maybe I should simply lock mine in the garage just in case eh?
One last point; there is nothing wrong with having an opinion but it doesn’t make you right.
