The A2 had a higher one, and then the B's went back to the A1's, you have to wonder why kawasaki did this????
A1 14 to 18psi
A2 16 to 21psi
21psi = 1.4479 bar
1.6 kgf/cm2 = 22.7573 PSi
1.6 Bar = 23.206 psi
I can only think that the extra psi may blow the pipes off, or bust the radiator or blow a seal in the cooling system somewhere.
So if you are going to use it, make sure your fans are working well to keep the temperature down.
For Tech Questions Bike Model letters are more useful than saying the year, for uk owners anyway, as registration year is not always year of manufacturer model.
