Our Speedster Mini Motorcycle Speedo’s feature 1.90 inches (48mm) diameter for a minimalistic look. Speed can be set in either miles per hour or km/h. If speed goes over 200, it will be displayed on the LED display. The LED dispay in the middle of the motorcycle speedo offers the following functions: total distance (odometer), maximum speed, on-board voltage, time. There are also four colored LED’s for oil pressure (red), neutral (green), high beam (blue) and turn signals (yellow). Our Speedster Mini Motorcycle Speedo’s can fit in our De Luxe Motorcycle Speedo Housing, Ring Motorcycle Speedo Housing and in our Alcatraz Motorcycle Speedo Housing. Speedo housings are sold separately.
