Tire pressure conversion chart (BAR to PSI)

Moto Guzzi Quota 1000 and Quota 1100 ES models

// //

The owner's manual states that the front wheel should be inflated to 2.3 BAR and that the rear wheel should be inflated to 2.5 BAR with one rider and 2.9 BAR with two riders. When running at continuous maximum speed, the pressure in the front wheel should be increased by 0.2 BAR.

But what is a BAR? To start with, BAR is a word in and of itself (PSI is an acronym for pounds per square inch). In short, 1 BAR is equal to about 14.5 PSI (14.5037738 to be more precise). Here is a conversion chart:
