I don't know of any Honda that has this
Contact Honda. Maybe they'll consider adding this feature to future modelsAnd they already have the voltage brought into the ECU / Display, so it would be easy. But then they don't display oil & coolant temperature either, so I think they deliberately "dumbed it down."
Seems like you could select if you wanted the numerical or dumb screen with one of the push buttons.
My guess would be that the CBR lineup was never intended to have a lot of electric add-ons and doo-dads attached and so the system loading was never anticipated to be such that a voltage display would be really needed.Why they did not make the battery voltage available on the display is beyond me - this would have been little or no cost and would provide the rider an early warning of a discharging battery.
People are often chided for not searching before posting. We should applaud those that post in relevant threads even if they're old(er).Zombie thread! Someone dug deep for this one.....
