Let's be honest: tire pressure's a pretty big deal for motorcycle riders. Garmin's Tire Pressure Monitor Sensor works with your zumo 390LM navigator to let you track your tire pressure. You'll need one sensor for each tire on your motorcycle or ATV, and your zumo will track up to four tires in any configuration. The sensor is not designed for automotive use or for tires with non-metal valve stems.
Just pair the sensor with your zumo 390LM, then screw the sensor onto your tire's metal valve stem. ANT wireless technology lets you see each sensor reading on your zumo's screen as you ride. You can set custom pressure thresholds and have the navigator alert you when the pressure changes. You can even track pressure trends over time, so you can spot a slow leak before it becomes a bigger problem.
The sensor is powered by a single replaceable battery with up to 18 months of life. Battery life is preserved when you're not rolling, and the sensor engages when your bike starts to move.
