Im sorry to hear about your keyless issue. I'll get that on mine as well but generally once it hits and you press the mode button to bypass it, it won't come up in your face again, unless you turn the bike off and back on.
One other thing I have noticed which I am sure really should have nothing to do with it is... it seems to happen more on windy days.
I have come to keep my key either in my left pocket, either pants or leather jacket, so it's right there near the sensor to try to minimize this.
Maybe this is something they should make it so it's just a little message at the bottom of the screen when you are driving and NOT this huge in your face forcing you to acknowledge when riding. I understand that yah, if you drop yoru keys while driving this could be a problem you need to know, but still. too annoying.
It's like microsoft mentality... your keyboard is missing...... press any key to continue.
