I can't seem to find it either...I see that Amazon has many of the Koso speedos and the one that works with Harley sensor is there. I think the one that I used was not one for a universal pickup. My main reason for having a speedo was for odometer (to estimate fuel levels). This setup works, but I was never able to get an accurate speed from the unit....funny thing is that odometer still appears to be working great. One of these days, I will dig into it deeper. To domover, I would probably look fro a speedo that is similar size, but not Koso. In one of my posts I talked about there very limited ability to support me during the install.
