Maintaining the correct tyre air pressure is very important as it can greatly affect a motorcycle's handling, and riding with low tyre pressure, due to a puncture, leak or other, increases the risk of a tyre bursting. Tyre air escapes naturally over time, so it is also important to check tyre pressure regularly. The Tyre Pressure Monitoring System continuously measures tyre pressure (using sensors attached to the air valves of each wheel) and displays the current pressure on the bike's instrument panel while riding.
Tyre air pressure varies greatly as the tyres warm up, but the Tyre Pressure Monitoring System takes this into consideration and recalculates the pressure for 20? to avoid confusion and false warnings.
When tyre air pressure is excessively low, a tyre mark appears on the display, warning the rider. On the 1400GTR / Concours 14, recommended pressure for both the front and rear wheels is 290 kPa (approximately 2.9 kgf/cm2). Should the pressure fall below 220 kPa (approximately 2.2 kgf/cm2), the warning mark will appear. Not only does this system eliminate the hassle of manually checking tyre pressure on long tours, it quickly lets the rider know of any sudden pressure loss due to, say, a punctured tyre.
