SpeedoDRD DRD-H1 SPEEDOMETE​R / Speedo CALIBRATOR Honda - See Description for Motorcycle Compatibility

Simple to set up. My 2002 CBR 954RR has a modified sprocket setup which caused the speedometer to be way overstated. This also causes your odometer to be overstated as well which is not good for the future value of the motorcycle.Just plugged it in to the factory harness. By using a GPS on my phone I figured out the difference between the motorcycle's speedometer and the actual speed on the GPS. I performed a quick calculation using a formula which is in the manual and then programmed the unit with a series of button taps. I've had it on my CBR 954RR for a few months and the speedometer is accurate. This is a great simple product that will make your speedometer accurate again and help maintain your actual mileage.

Relatively easy install on my 2008-GL1800-HPNA. Once install, checked speed with GPS and calibrated the device to show correct speed. Very easy to configure and now have correct speed displayed on the speedo!

Good, solid piece of gear that is great for correcting the factory speedo settings, which are typically off by 5-8% The only negative is that the directions make install sound super easy... and for most bikes it is. I ride a CBR F4i and the install was obnoxious. Not the products fault but I do believe the company should include pictures with the directions...

Nice Product. Works great Easy to use and install

Installed on two different model bikes, easy wiring and installation with factory clips. Easy setup, and accurate speedometer readings.

Anytime I get a new bike or I change up my sprockets on one the SpeedoDRD is one of the first things I get. Very simple installation and set up.

Works Great on a Honda GL1800

Very small and easy to tuck away nearly anywhere. Truly plug-and-play. Programming was a snap with the directions that came with it. Corrected my speedo error throughout its range from 25-80+mph.
