OFF / RUN Switch
Does anyone here, with experience, understand the purpose of the off/run handlebar switch other than maybe an emergency engine kill switch? After decades of riding earlier bikes that only had an ignition (key) switch, I fail to understand why the owners manual says I should use this switch to stop the engine, but it doesn't say why. The ignition switch alone seems to work just fine. I would appreciate a technical reason or answer instead of guesses.

RE: OFF / RUN Switch
All of my older Harley's just had the 'ignition switch', and as you said, it wasn't until recent years that HD started using 'kill switches'..
I think it's just a safety (or emergency) switch to kill the engine if you run into a problem, much like the 'bank sensor' that will kill your engine if the bike is tilted beyond a certain point.
That being said, I never use the bar mounted 'kill switch' when stopping or starting my bikes.

Thanks, OFG. I have never used it. Just thought maybe there was something logical I didn't understand. Seems like something else to break IMO.

It's for safety, should the bike still be in gear and your left hand slip off the clutch lever while leaning over to the right to reach the key the bike would jump forward and down you would go. It is much safer to kill the engine while both hands are still on the bars, then reach down to shut off the key with the engine already off.
PS I never use it either unless I am working on the bike with the power on and don't want it to accidently start if I happen to bump the start switch.

there have been issues with speedo and tach due to the shut down sequence. I am sure if you pull your manual, it will state the sequence.

I don't know why, but I always use it. I only turn the key back when I'm removing it. For me, it's habit now. IF I'm ever in an emergency where I need to shut it down, my first thought is the kill switch, not the key.
