Sorry got a 1199s with no frame so to speak will just keep looking thanks anyway. To all the comics Don't quit your day jobs ;-)
on a serious note then, get a tinted screen on the bike and put the disc on the inside, it doesn't stand out and is technically still visible......just not immediately obvious
I fitted mine to the bolt securing the hugger, you would hardly notice it. as you know the cops over in our neck of the woods like giving out fines for not displaying.
If you're lucky enough to be a Desmosedici owning Ducatista, the problem of where to displaythe tasx disc is a very significant one....there's nowhere to fix it at all!
Here's where I have mine. As suggested Oberon/Oxford tubular holder inside the frame on the right side of the bike. Had to file a small part of the holder to make it fit snug
