I've heard all kinds of weird things about why the kill switch exists, from "It's the primary way of turning the bike off - It's the E in the MSF FINE-C process" all the way to "It's only to turn the bike off if you feel you are falling off" I've always used the kill switch to turn the bike off and left it in the off position while parked. It's right there, so why not? Turn on: - Key in, turn to Off the release steering lock - Get on bike, rock it off the center stand - Key to Run - Neutral - Engine switch to RUN - Starter Turn off: - Engine switch to STOP - 1st gear - Kickstand down - Get off the bike - Pull the bike up onto the center stand and stow the kickstand - Turn the handlebars full left, turn key from Run to Lock and remove key.
