The service manager at our local BMW dealership here in Virginia was struck and killed by lightning last year. He was on an R1100S, riding at 60 mph. He wasn't even the tallest object in the area because there were trees and powerlines on both sides. We miss him still. So it can and does happen. I use to ride right thru thunderstorms, but not anymore. Lightning awareness is necessary.
And no, there is no faraday effect that the external body of a car offers, on a motorcycle.
