Old Ducati

I saw this while visiting a sandwich shop, AK Subs, south of Market in San Francisco.

Sorry for the quality, it is a cameraphone. At first I thought it was an old BMW but then I noticed the awesome paint job and emblem on the tank; it said Ducati. The best part was that it was gone when I was done eating. This person really rides it around, and anyone familiar with downtown San Francisco knows that the road conditions here are hard on a motorcycle. That seat doesn’t look like it dampens much of the bumps! Does anybody know the age/history of this bike? Maybe Twisting Asphalt knows . . .
