I have a GPS and use it all the time. The speedo on the bike was always 4 to 5 mph off at highway speeds. The last time I replaced the rear tire I put a 70 series on and the speedo reads true now. I am unfamiliar with the Speedo Healer. The GPS always reads the correct speed but lags behind a bit, takes it a couple seconds to catch up.
