The factory black and white Ducati 900SS is a very rare combination and highly sought after because it's a dead sexy combination hardly ever seen in the wild. Unfortunately it seems only the 1992 model received that treatment from what I can research. Nonetheless, it looks very well looked after and worth a look for $4300. It's in Everett, Washington on Craigslist:
quote from seller's Craigslist posting:
1995 Ducati 900 SS/SP in very good conditio with 10961 miles. Within the last 1500 miles it has had new tires, chain and sprockets, belts, tune up, carb cleaning, clutch cylinder rebuild, and oil and filter change. The only thing that might need attention is the rear brake that squeals at low speeds.
I've desided I need a bike with a more upright riding position, so I'm putting this one up for sale.
