42 psi at both ends. Yamaha recommends 36F/42R, but I find that most tires on this bike will cup/brake wear on the front at that pressure, on that bike. I check pressure at least weekly, as bike tires tend to lose a pound or so a month. More than half of the bikes that come onto the shop that we check have tires that are 20% or more below the recommended inflation pressures(as marked on the frame sticker). I'm looking forward to replacing the current set of PR2s with PR3s, probably about 3 weeks from now(about 18k on them as of this evening).
