What It Is / How It Works

This digital water temperature gauge is a 12V motorcycle thermometer that shows engine temperature on an LCD readout. It is designed for 12V motorcycles and scooters and uses a threaded M10 sensor. Digital gauges of this type replace a needle with a numeric display, so the reading is shown in exact degrees rather than estimated from a dial.

Who It's For / Use Cases

Riders of 12V motorcycles such as the XMAX250, NMAX, CB400, or CB500X who want a direct temperature readout will find this useful. Scooter and racing bike owners looking for a simple plug-and-play upgrade are a good fit, as are DIY mechanics who prefer a waterproof gauge that installs without complex wiring.

How to Use / Care

1. Install the sensor yourself: the threaded M10 sensor and straightforward wiring are designed for most 12V bikes, so a mechanic is not required.
2. Read the digital temperature on the LCD screen at a glance while you ride.
3. Watch for the flashing warning, which activates when the temperature goes above 120 degrees Celsius.

How to Choose

Start with voltage. This gauge is designed for 12V systems only, so a 6V motorcycle is not a match. Next, choose the display color: red or blue for an LED look that suits your bike, or black as the other available color. Finally, confirm your bike or scooter has room for an M10 threaded sensor, since that is the sensor size this gauge uses.
