Don't know what your experience is with the keyless, but it seldom works first try. It's a cool gimmick but a key works better imho. Also, turning the bike on and then off again is a bit silly to put the steering lock on.
Don't confuse the Energica issue with other keyless vehicles. I have such on my Harley and it works great, at least until the battery in the FOB gets weak (then the FOB must be away from the bike to put in my PIN code). A dead FOB battery would cause no such problem, just when the FOB battery is weak, it then won't let the bike start even with a pin code). This is a minor issue, IMO, at least when one knows that can happen. I prefer the FOB to keys by far.
My Chevy Bolt also uses a such FOB. Works perfectly every time (so far).
I also have a FOB for my Tesla M3, but it's a stupid type where I need to press the button on the FOB to drive the car or unlock the doors, trunk or frunk. Still better than a key (or any of the other Tesla non-FOB methods, IMO).
I have heard about the issue in the Energica. That is NOT typical with keyless. I am assuming Energica fixed that issue with their new Experica. They must know about it and realize it needs fixing by now.
