Building a custom bike, kart, or small vehicle? The Koso EX-02S speedometer is a popular, feature-packed choice. It’s a compact digital dash that shows speed in either km/h or MPH (up to 360 km/h or 225 MPH), plus it includes a voltmeter, clock (12/24hr), and even a stopwatch function. The display is clear and backlit, so you can read it day or night. It also has indicator lights for high beam (blue), turn signals (green), neutral (green), engine warning (amber), and general alert (red). The whole unit is small – about 4.7 x 1.6 x 0.9 inches – so it fits on cafe racers, dirt bikes, ATVs, go-karts, or custom projects without taking up much space. Wiring it up is straightforward if you’re familiar with basic electrical: it runs on 12V DC and uses a standard sensor for speed pickup (sensor not included, FYI). The housing is durable plastic, and it mounts with brackets or adhesive. Whether you’re replacing a broken OEM gauge or adding instrumentation to a DIY build, this gives you clean, modern readouts without breaking the bank. It’s universal, so no make/model restrictions – just make sure your speed sensor signal is compatible. Reliable, good-looking, and way more affordable than some brand-specific units. Gearheads, this one’s for you.
