Just had a look in the 998 owners manual that comes with the bike.
Front 2.1 bar
Rear 2.2 bar
To Convert to PSI x 14.5
so Front is 30.45 PSI
Rear is 31.9
Manual also says put 0.2 to 0.3 bar more in to "avoid front wheel rim distortion when riding on bumpy roads"
Maybe PB know best
Don't know if the 916/996/748 manuals recommend something different.
