I picked up a speed hut speedo/tach combo for a cafe racer, the big one (3 7/8?) and had them remove the "speed hut" logo but keep the "made in USA" stamp (not a fan of logos, I'm paying cold cash and don't really entertain the fact they 'advertise' on said product, without paying me in cold cash. I haven't figured how to mount the gauge yet, but I'll be putting the sensor thru the top tube and under the seat. One BIG THING to consider, is they aren't weatherproof. You'll have to send them out or do it yourself if its a daily driver.
