I strapped a pair of Wolfman tank panniers to the bike to see if they would work. The bags can be made to work, but not without some modification. There are couple of issues.
1. The upper straps pretty much have to be placed on both sides of the tank cap, which places the bags a bit too much backwards. The issue is that even with my short legs my knees don’t really fit behind the bags. The top straps can’t be moved any further forward as they would interfere with the steering. Mounting the bags solely on the side fairings feels like a bad idea.
2. Because of the fairings, there really aren’t any well located spots to tie the lower straps to. Cutting some holes to the fairings could sort of work, but the fairings are sort of flimsy if you are planning on placing anything heavy inside the bags.
If you want them Amazon has them for around $100:Wolfman Tank Panniers
