This digital tire pressure gauge is from CruzTools so you know the quality is there. The gauge reads accurately from 3psi up to 99psi so it can be used on all kinds of tires. However, it's size - only 3-3/8" high and 1-3/4" wide makes it perfect for storing in the saddlebag or tool bag for use on your cruiser or touring bike. The large display is easy to read and the automatic shutoff means it won't have a dead battery just because you forgot to turn it off the last time you used it. It displays tire pressure in PSI, BAR, kg/cm2 or kPa and holds the reading even after you remove it from the valve stem. You also won't have to scroll through all of the displays each time you use it because it powers on displaying the same scale you used last time. A indispensable tool for anyone that rides a motorcycle!
