Gerauld Rack: $90. This was an add on to the SR357 rack. I believe it strengthened the entire subframe. Gerauld is awesome. I asked him to create a fuel rack for me that would attach to the rack he already made for me. This is what he came up with. Everything fits perfectly. It came powdercoated with great looking welds. I did have to screw the "legs" of the fuel rack to the SR357 rack. Otherwise, it is bolted and screwed on the rear rack and can be taken off in five minutes if you need to carry a rider or just don't want to carry it. Not sure if you need the other rack for it work. If you talk to Gerauld he can fabricate something for you I'm sure.
