The Koso XR-01S Universal Fit Speedometer (BB026001) is thinner and lighter than its previous version. Koso's innovative XR-01S Speedometer features most importantly a larger, higher quality, and easy to read LCD display. The indicator light functions are still there; however, Koso has added one more, which makes a total of 6 indicator lights. New interesting functions were added and they include a 2 hour meter reading, a maintenance hour meter for oil change, 2 trip meter readings, and a useful clock. The XR-01S is simplicity at its best. This meter is user-friendly, easy to read during day or night, and is a great fit for any kind of motorcycle, scooter or other bike.Click here for installation instructions.
