I have had "speed bleeders" on most of my bikes, including my BMW R1200GS which has the ABS system. I have had no difficulty bleeding the brakes in less than 10-15 minutes per axle.
The key is to bleed not only at the caliper, but also at the master cylinder. I generally start with the master cylinder as any air/bubbles tend to elevate in the system and are located in close proximity to the master. Thereafter, i go to the calipers and bleed a lot of fluid to insure i am flushing throughout including the ABS . Do not be afraid to flush a lot of fluid.
