I didn't do anything but give him the tire, haven't even seen it mounted.

I doubt it lists those pressures for all conditions. Sure you're not leaving out the fact that it's talking about when you're riding 2-up or something?

I would use a car's owner's manual for tire pressure recommedations, but not a bike manufacturers. All sportbikes weigh within 50 lbs of each other these days, so why would one bike recommend 36/42 and another 32/36? It wouldn't make sense. I would pay more attention to the tire company's recommendations. Each tire is different, for example I think Pilot Powers recommend higher pressures than most brands.

And besides, like I said, I already run 40 or so for commuting, but I would never do that for a spirited run. Go to any track day, and regardless of whether you are just using street tires, they will tell you to lower the pressure to get more grip.

Check the fender clearence too, the 120/70 is a tad taller sidewall but it shouldn't be an issue if it has stock fenders.

edit: nevermind, clearence won't be an issue going TO a 120/60
