Ah - sorry about that then, must have looked at your account wrong.I'm not new, in fact I joined before you ;-) but haven't had anything of interest to post until now.
And no, it's not an advertisement - apologies for forgetting the brand which is Hepco & Becker.
I saw a different picture of the motorcycle with these bags in a German magazine (the bike, called the Ducati Scrambler Duster, is from a German customizer, LSL-Motorradtechnik). I wrote to H&B because I couldn't find the bags in their web shop. They immediately wrote back to tell me they're part of a new range called Legacy, will be presented at the EICMA in Milan and be on sale in Spring 2016. I will be buying them for my Ducati Scrambler Classic.
Also very nice bags but I find the H&B ones more retro looking. As in all things, beauty is in the eye of the beholder......
In the magazine pictures the two H&B Legacy saddle bags are joined by two leather straps which are slung over the saddle. It doesn't look like they need a mount; however these bags could be prototypes. We'll know more soon when the Legacy range of luggage will be presented at EICMA in November.The SW-Motech have an added advantage over the H&B, they do not need to be used with any sort of mount, instead they are fixed to the seat.
