I'm in need of some panniers for my GSW and I'm waiting for ones with the exhaust cut out. In the meantime, I've been looking at soft saddle bags. Most state they require a frame of some sort but I noticed the Enduristan Monsoon 2s you have say they don't need a frame if there is enough clearance from the exhaust.
Do you think they will work on a GSW? Could you test it out on your bike?
