Stilltime - As everyone else is say, "Really great looking bike".
Recently I spoke with SpeedHut for a speedo/tach for my BMW project. They advised me that the smallest GPS speedo they have, that still has an odometer in it is 4". They have some really beautiful 2-1/16" units that are GPS-based, but they don't have space for the LCD display until they get to 4".
Don't know if you discover anything different, but if you do, please post it up. I ended up going with MotoGadget Tiny for that build as a result, but have 2 other bikes that I'm seriously looking through the Speedhuts for...
