New for 2019, SpeedoDRD has been decreased in size to only 20mm square and epoxy sealed with weatherproof device connectors; making it the smallest, most durable, and most feature packed device on the market.

Note: The SpeedoDRD cannot alter your existing odometer readout. The SpeedoDRD corrects and fixes the speed signal after it was altered by something else, such as sprocket changes or tires size changes or transmission changes.

If your vehicle model & year is not in the list, you will need to order the Universal Kit. All other models listed in the drop down list are Plug and Play Motorcycle Models. If you order the Universal Kit you can specify your vehicle model & year in the checkout notes. You can also contact us to inquire if we have a plug and play solution in the works for your model.

The Universal Kit does require some basic wiring to install. It's fairly easy, and only 4 wires; [positive, ground, signal-in, signal-out]. Universal Kit works for Cars, Trucks, & Motorcycles with digital odometers, and 3 wire speed sensors.

*SpeedoDRD Model A1 is plug & play for Harley Davison motorcycles (1996-2006) which have the 3pin triangular Deutsch Speed Sensor connectors are shown in product picture.
