The Koso Tachometer is a motorcycle tachometer built around a stepper motor for stable, precise RPM readings. Its needle response is designed to stay smooth across engine speeds, including on vibration-prone V-twin engines, giving riders consistent data they can rely on while riding.
Night riding is easier with an illuminated needle that keeps RPM readings clear in low light. The integrated LCD screen also displays a digital odometer and trip meter, so mileage information is available at a glance. An auto-scan function activates automatically when the engine starts.
The tachometer works directly with existing OEM speed sensors, which makes installation a simpler upgrade for the rider. With its robust, road-ready design and easy-to-read features, it is a practical choice for anyone wanting a clearer view of engine speed and trip data.
