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.

we always used a small battery, something like would fit in most every bike. never one big enough to start a 4 wheeled vehicle.

As long as the car is not started you will not hurt the bike. Period. For the record I got a 4.0 from NIT for electronics. If the car is not started it will not hurt the bike.

The only reason the running car will hurt the bike is the cars charging system does not hold a constant voltage and that voltage can be too high. The amperage has nothing to do with anything. Just like in a house if you plug a lamp into a 15 amp circuit it lights the same as a 20 amp circuit.

Best way I can explain it is the voltage is like the pressure in a water hose and the amps are the amount of water in the system before you run out. The pressure can cause problems having a larger volume at the supply with hurt nothing.
