Received and installed an
SW-Motech PRO City tankbag on my 1300.
It's not on the recommended list from the fatherland, but it fit quite well and offered only minimal interference at full lock with MCL bar risers installed (not sure which revision I have).
I had to remove a RAM mount from the clutch lever clamp and reposition my ebay switch bracket from below to above to prevent serious full lock inference on the clutch side. As installed the down windshield button contacts first and neither the horn or turn signal buttons contact the bag due to the shape of the switchgear pod. On the throttle side, the starter does not contact the bag either.
I'm very impressed with the design and construction quality of the SW-Motech products and I'm excited to spend some time with it.
The only thing keeping me from running wild with the PRO City (11-14l ) is that they also sell the PRO Trial (13-18l ). I'd like the larger bag but its width at the front is about 1-2" greater, right where any interference would be the worst. I need to visit their showroom in Portland, OR to test it to know for sure.
However, as is, I can recommend the SW-Motech PRO City tankbag for your ST1300 with or without bar risers (note, my risers position them back and up, so my photos show what I think would represent a worst case scenario).
