Has anyone tried a Famsa tank bag. I saw them advertised the Bikerworldusa web site (www.bikerworldusa.com) which also advertises in the ON magazine. I believe they're made in Italy. According to the website, they're half the price of the BMW bag. I'm looking for a bag for my 1150RT plastic tank...or I would have bought a cheap Cortech for a $120. I really don't want to spend $400-500 for a tank bag.
