This incredibly small digital speedometer is perfect for a wide variety of custom applications - including installation directly into the top triple tree. It can toggle through multiple functions including speed, odometer, tachometer, trip and time. In speed mode it also displays a bar-style rpm read-out. It can even be set to flash when you reach your preferred shift rpm. Includes a magnetic reed-switch speedo sensor, but is more regularly used with your bike's own electronic speedo sensor. Very easy to calibrate resulting in a very clean but very functional product.
