Here's a bike that's unusual enough that we had to go dig out the reference books to figure out exactly what it was. Yes, this looks like a cross between a Ducati Darmah and a 900 Super Sport, and that's because it basically is.
Made from 1978 through 1981, the 900 Super Sport Desmo Darmah used the engine and drivetrain from the regular 900 SD, without a kickstarter. According to The Standard Catalog of Ducati Motorcycles by Ian Falloon, "The bodyworkd was based on the first series 900 SD, with the same fuel tank, ducktail seat, and side covers, but with a Super Sport-style half fairing. The suspension was also identical to that on the 900 SD of the same period with a Marzocchi fork, and Marzocchi oleo-pneumatic shock absorbers."
The few photos of this model in the book and online that we've been able to find all show a silver paint job with blue dashed stripes, but the auction states that the red paint on the bike in the auction is original.
Falloon's book also adds this final note: "While undoubtedly one of the most attractive Ducatis of the era, the 900 SSD was too heavy to be a real Super Sport, and its overall performance inferior. Management decided the 900 S2 was the future for the bevel-drive twin, leaving the short-lived SSD as one of the rarest bevel-drive twins."
According to the auction, this bike has just 8,969 original miles and is in mint condition with factory Coni pipes and a new battery.
