I guess I'm not clear what functionality a key fob really provides for a motorcycle.
On my car, I walk up to it with the fob in my pocket, touch the door handle, the car beeps and unlocks. Then I get in and push a button, and again, because of the proximity of the key fob, the car starts and runs. That already seems marginal in utility. Pushing a button is somehow better than turning a key? I guess it's cool that I don't have to dig my keys out of my pocket.
On the bike, I suppose if the key fob is near, pushing a button would start the bike and unlock the fork, rather than turning the key. So again, I suppose it's nice that I don't have to dig the key out of my pocket.
I guess I don't see that that tiny bit of convenience is worth the extra expense, weight, and complication of creating an always-on power supply on the bike (so it can recognize the proximity of the key fob), a solenoid to lock/unlock the fork, and anyhow I still want a key as backup for when the key fob battery runs out or the key fob gets crunched or dropped in water.
I'm an incredibly lazy bastard, but I'm really okay with digging my key out of my pocket.
