I've got a set of these mounted on my B1250--SW MOTECH makes a removable mounting system that fits these bags specifically and also for the B1200s (got mine through Twisted Throttle). With the racks off, you have small (>3" mounting bars on the passenger pegs & grab handle; U bracket on the rear fender) pieces left that are easy to miss. You just need to be careful to ensure that the exhaust can is low enough that it clears the right bag. Very stable and secure.
