KOSO Water Temperature Gauge | Motorcycle Temp Sensor for XMAX250 300 NMAX CB 400 CB500X

Keep your engine running at the right temperature with this KOSO-style water temperature gauge. It gives you a clear, real-time reading of your coolant temperature so you can ride with confidence and avoid overheating issues on the road.

This gauge is built with a high-definition LCD screen that shows temperature data accurately. When the temperature goes over 120 degrees Celsius, the meter starts flashing to warn you right away. That early alert gives you time to pull over and check your bike before any damage happens.

The design is simple and professional. It is waterproof and safe to expose to sunlight, so it holds up well in different weather conditions. It works with most 12V motorcycles, racing bikes, and scooters, making it a versatile upgrade for your dashboard.

You can choose between red or blue LED display colors to match your style. The gauge uses a reliable temperature sensor probe that fits common radiator hose sizes. Installation is straightforward for anyone with basic mechanical skills.

Usage Scenario

Luis was cruising through city traffic on his XMAX300 when he noticed the engine felt hotter than usual. His stock dashboard had no temperature readout, so he had no way to know if things were getting dangerous. After installing this KOSO-style water temp gauge, he now sees the exact coolant temperature at a glance. One afternoon, the gauge started flashing at 120 degrees, giving him enough time to pull over and let the engine cool down. That simple warning saved him from a costly repair and a long walk home.

Micro Comparison

Unlike basic temperature lights that only tell you something is wrong after it is too late, this gauge shows the actual temperature in real time. It gives you a numeric display and a flashing warning at 120 degrees Celsius. That extra visibility helps you catch overheating early and take action before your engine suffers.
