Man, that's cool. It's what I asked about here about two years ago. I wanted one for my cafe' racer. Actually, I'd like the small digital display without the analog part. I have an analog tach (not hooked up yet).
Any GPS will monitor speed with a digital readout –
Why not just eliminate the superfluous crap
& hardwire / mount a GPS behind the fairing or on the 3-tree ?
More info & less junk.
