I had a job getting mine off as well and resorted to the method you described.
Mine is a '98 model with the 9mm nut. As yours was torqued up over 150Nm could this be the actual cause of the original 9mm nut problem? Maybe they were overtightened at the factory knackering the thread on shaft and nut leading to the nut coming loose? When you replace with the 12mm nut maybe it's relying on the good thread that's still there on the end of the shaft? I'm new to this bike, so just throwing this in as a possible cause of the problem.
It's not the cause as I torqued mine correctly and then rode it briefly and ended up with it tight again. It's physics, blame Newton not Yamaha :-)
