Just like was said. It would be safe to jump off any batt. Does not matter what size if it's 200cca or 1200cca. It is still 12 volt. Your starter will only pull so many amps. But yes hooking up with car running and alt on car putting out 14.4v may cause some problems you do not want to deal with.

If it was my only choice because I was in middle of nowhere - sure, but DO NOT START THE CAR'S MOTOR because the extra power from the charging system will possibly destroy the motorcycle's charging system and could cause a fire. The car battery should have enough power to start the motorcycle without the car's motor running.
I concur with this. Jumping off your car is not really a problem just don't start the car because damage can occur to the electronics.

Dam I wish this thread would have started yesterday.
I boosted my bike for the first time ever with my Jeep and I had it running! I hadn't ridden for a couple of weeks and my POS battery tender is a worthless POS.
Luckily nothing bad happened. My regulator still shows an output of 14V.

Yeppers, you can jump any 12V motorcycle with any 12V car battery. 12VDC is 12VDC any way you slice it. The bike starter wont pull any more amps than it would from the bike battery, well for the sake of keeping it simple and to the point, let's just say this is true and save the technical end for another time. Like was said earlier, I don't recommend running the cage.
