There is a post somewhere with shift points noted, I can't remember where though. First gear should be only to 15mph, 2nd to 25, 3rd to 40? 4th to 50? 5th to 70?? I don't know, but that should be safe. If going up a hill, change down. Lugging an air cooled engine is not a good idea.
I have lost all but 15% of my hearing and I just picked up a 06 Electra. This bike is so quiet and with the wind blowing on my hearing aides I cant tell when to shift. If someone could give me some MPH shift points it would sure help.
