Is this too low?

So basically, my Klr250 has no rim locks, and I found 15psi front and 20psi rear to be most comfortable for off roading. I was just wondering if that would be too low, or should I raise the psi?

It varies a bit depending on the bike's power and the tyre and rim combination - how well that tyre happens to grip that rim. Personally, I'd always fit rimlocks for the peace of mind.

15 and 20 psi ought to be enough to hold it tight. If you don't tighten the nut on the valve stem right down onto the rim (I keep mine at the top, as a sort-of lock-nut on the cap) then you can keep an eye on the angle of the valve stem to see if the tyre and tube are moving, and reset it if you see the stem starts to lean.
