What It Is / How It Works

This mini motorcycle water temperature gauge shows coolant temperature on a compact LCD screen, so you can watch engine heat while you ride. Gauges of this type give a precise number where a stock dashboard may show only a generic warning light.

Who It's For / Use Cases

Riders of motorcycles and scooters who want a dedicated temperature readout tend to get the most from a gauge like this. It suits daily commuters who sit in stop-and-go traffic, weekend riders who push their bikes harder, and DIY owners who want a simple way to keep an eye on the cooling system.

How to Use / Care

1. Mount the gauge on the bike using its M10 thread, then check the reading as you ride.
2. Watch the display during stop-and-go traffic or long climbs to see how the reading changes.
3. If the display flashes, the temperature is above 120 degrees Celsius, so pull over and let the engine cool down.

How to Choose

Start with the electrical system. This gauge is designed for DC12V systems only, so a 6V motorcycle is not a fit. Next, confirm the cooling system has a port that takes an M10 thread.
