What Does It Do?
Whether you're dealing with a motorcycle that comes from the factory with a speedometer that reads too high/low (like most do), or maybe you've changed the gearing and/or wheel/tire size on your bike and now the speedometer / odometer are no longer accurate... the SpeedoDRD from 12oClockLabs solves your problem! These devices are also popular when converting your bike to a supermoto with 17" wheels and tires, because that throws off your speedometer / odometer.

Cost Effective: The SpeedoDRD is the most cost effective solution on the market today, without sacrificing any features.

Simple: The SpeedoDRD is easier to setup than any other devide on the market. Simple plug-n-play installation using factory OEM connectors.

Accurate: SpeedoDRD allows speedometer correction in 0.1% steps, up to 99.9% + or -

Tiny: SpeedoDRD is the smallest digital speedometer calibration device in the world...easy to tuck away just about anywhere on your motorcycle.
