In professional motorcycle road racing, the air pressure in our tires is one of the most looked at and important tuning adjustments we make. On any given day, we may check the pressure in each tire 10-20 times depending on what we are trying to accomplish. We need a pressure gauge that is quick to use, dependable, highly accurate and quick to make adjustments. Motion Pro's Tire Pressure Gauge is tough and built well, without being excessive. Its ergonomics are great and there is a easy to reach button to let air out while still monitoring the pressure. The flexible hose makes it easy to reach valves of all types in tight spaces.
