I'd like to add something into the mix, if I may.
How would jumping a bike from a car battery be any different to the electronics than jumping a car from another car/truck? The electronics inside the ECM/PCM are the same in either, are they not? I mean, a circuit is a circuit, a capacitor is a capacitor, a microprocessor is a microprocessor and so on. How would either of the two be any more fragile than the other?
I understand that you are looking at the AH of each battery and all, but afterall, they're both 12v systems and they work the same.

How do motorcycle dealers jump off a bike if they need to do so quickly? It may be worth a call to a dealership just to see what they say.
