I used to run one bag on my old rigid Pan with upswept fishtail pipes. Looked just fine and was practical.
So is the previously mentioned price for one or two bags?
One bag. Everything is quite expensive here in Sweden. I had to pay 580 for it. It's the largest model. I'm sure the other models are cheaper, but I really think the size of this one fits the Fat Boy model well.
have to add that I love mine. Got the Bamse also and it is a beast. By far the most rugged and sturdy piece of luggage ever. Never understood why in the States you can't find a bag like this. For a while there I was thinking about making a bag like this with heavy saddle skirting. Then I saw these when I moved to Sweden.
