My dream bike would be painted all flat black. It wouldn't have a gauge cluster at all. HUD would have 2 modes. Mode 1 would have minimal info on it such as MPH, RPM, and TEMP.
Idiot lights would light up at top of HUD for oil pressure, overheat, turn signals and high beam indicator.
You could press a button on side of helmet to go to "advanced mode" which would display all the extraneous stuff such as trip meters, odometer, fuel level, etc. for mode 2.
Oh, and the transparency would be adjustable.
