How does the FJR/Super Tenere starter/kill switch work? One push starts the bike and a second stops it? Practical but it loses the headlight flash to pass function. Not a big deal I guess as most riders probably don't use it anyway.
It's essentially a 3-position rocker switch. Rocked forward it kills the ignition, rocked back (middle) puts it in the run position. So far this is the same as the ST1300's kill switch. With the FJR & Super Tenere (and probably other Yamahas), instead of a separate starter button, you just press the rocker a little bit past the run position to activate the starter via a momentary contact switch. To kill the bike you rock the switch forward just like the ST1300 and about 99% of the bikes out there. I haven't tried pressing it while the engine is already running to see if it flashes the headlights off and on or not. There is however a momentary flash to pass function built into the H/L headlight switch on the left bar.
I don't think I've ever seen a spring loaded kill switch. Does this mean you have to physically hold the switch in the kill position until the engine stops?
Having an integrated start/kill will save someone from the embarrassment of trying to start a bike where the switch is off but does not do much for accidentally hitting the kill in the middle of a ride. Fixing one problem doesn't help another.
I fail to see the difference in potential for accidentally hitting the Yamaha's kill switch vs. the ST1300s. If you are saying the potential to do so is the same then I agree. If you are trying to say the Yamaha design create a new problem, then I disagree. I actually accidently hit the kill switch a few times on my ST (leaving me scratching my head for a split second as the traffic behind me suddenly grew closer), but so far it has not happened on the Tenere, even in rough off-road stuff. There's no way to crank the engine on the Yamaha with the ignition killed with this design, such as one might do to perform a compression test, but the ST's starter button is disabled when its kill switch is in the off position anyway so that's a wash.
