New for 2020, 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 an 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 may 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 U1 (Universal Kit 1) 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 square wave speed sensors. For more rare 2 wire inductive coil sine wave sensors order model U2 (Universal Kit 2 [not to be used on ABS sensors])

The SpeedoDRD multiplier/divider feature is a special application feature that allows users to do complete gauge cluster or transmission swaps with vehicles that have completely different PPM (pulse per mile) rates, no other calibration device has a wider frequency adjustment range.
