Engrave the the "clutch switch plug" diagnostic on your frontal lobes. It'll save you a huge amount of grief, just as did for me; I was already planning out calling a tow truck, getting the bike to the dealer, logistics... and then got smart and looked at Stromtrooper.
Symptoms: bike won't start, headlight dims when you try to start, panel is fine, battery is fine, start/stop switch is fine.
Solution: push in the tiny little plug by the base of the clutch lever till the little bugger clicks into place.
Required knowledge for Strom owners, IMO.
