are there bikes with fuel guages, and if so do they have "reserve tanks"?
My Honda Blackbird has an analogue fuel guage with a 'low fuel' light within the guage, just like my car. The Honda VFR I recently owned had a digital LCD fuel guage, and the last 'segment' would flash as a low fuel warning.
I think it's a while since bikes had a physical 'reserve' tap.
