Re: Stelvio out and about pics here...
I got the Givi Sideracks and an SW Motech Adapter for the Trax Bags. The Givi Sideracks are widely available, and Twisted Throttle has the adapters, so you can use the Givi racks with Trax Bags. They also have adapters for a few other brands of bags. Given the unavailablity of the OEM bags, I figured this is probably the way to go, especially since you can get the Trax in Black (same as OEM) or silver (looks better on a black bike, I think) and smaller or larger sizes. My adapter wasn't a perfect fit (had to drill two of the holes to widen them a bit), but otherwise works very well. And it doesn't make the bags stick out any more than than they normally do. I don't have a picture but I'll try to post one at some point....
