Although worthless, this is my experience
When i received my keyless GS i did wonder how this would improve things.
First i like that i dont have a bunch of keys hanging out of the bike and scratching things or someone grabbing them (happening to a mate years back at a red light)
i also like just leaving my keys in my pocket all the time, i can put them in my safest pocket and its doesnt matter if its zips and velcro thats hard to open with gloves on
Now, i did have an issue at a petrol station once.... my own fault for not RTFM
i couldnt open the cap and was getting a little embarrassed as a car was behind me.
I was trying to open the cap and the ignition was still on lol, i basically pulled up left the bike in 1st and killed the engine.
Ive since learned that it opens every time 2 seconds after pressing the ignition button to off
2 things i would like BMW to change though......
The button moving, i know its not impossible to reach but its a little obscured by the bars, worse if you have risers.
as i said above i can keep my keys in my pocket.... unless im using my panniers then the keys have to be used, would be nice to have keyless panniers or at least locks we can buy to fit.
Would i request a keyless bike next time? absolutely.
i wont request a BMW sat nav though, i paid £550 for a sat nav and end up using my phone almost every time. thats another story!!!
