I did a search on Kill Switches but couldn't find an answer to my question which is: What is the purpose of using the kill switch for turning the bike off? I've been riding 40+ years and never use the kill switch for this purpose, I was always under the impression that it's main purpose was to "kill" the bike in an emergency (laying it down). The main disadvantage of using it in my opinion is that you may forget to turn off the ignition switch causing the battery to run down (which in my case it's called a "senior moment"). I noticed that in the manual of my new '08 RK it does state: "use the kill switch to turn off the bike". Is there any technical reason that one should do this rather than just using the ignition switch?
Well I'm not sure about this and I'm no electrical guru but I think I remember reading once that using the kill switch eliminates the load on the ignition switch thereby eliminating any arcing of the contacts in the ignition switch when you turn it off.
1. Flipping the kill switch is part of my start routine. There is always that dip stick in the crowd that like to flip the switch on a parked bike to see that look on your face when the bike doesn't start.
2. The action of using the switch helps to keep the contacts clean. If you ever need the switch, it will work.
I never use the kill switch either. For years now HD's has had a tip sensor that kills the engine if the bike is lay down or falls over while running. It's personal preference.
All of the above seem to me to be interesting and valid reasons for having a kill switch mounted on the bike. I have to wonder though, if the primary reason isn't a question of liabilty and or requirement by law. Color me cynical but this seems a motivation for the various MC manufacturers to spend the money on safety features rather than solely out of the goodness of their heart. Generally speaking, it makes sense to me to have redundant safety features even something as simple as to points of egress on a cage or in a house.

The main reason is because your manual says to use it.
I use both switches as part of the shut down and re-start sequence. Just a series of steps I go thru, kinda like a habit. Same steps every time. That way, I never forget anything.
