BaT Auction: 1981 Ducati 900SD Darmah
This 1981 Ducati 900SD Darmah is powered by an 864cc L-twin mated to a five-speed transmission and finished in black with gold pinstriping and polished fenders. Equipment consists of gear-driven camshafts, electronic ignition, Marzocchi suspension, Brembo brakes, and a two-up seat as well as modifications such as Silentium mufflers, K&N pod filters, stainless steel brake lines, and an Electrosport regulator/rectifier. The bike was acquired by the seller in 2019, reportedly following over 25 years of storage in Oklahoma. Subsequent recommissioning work consisted of rebuilding the carburetors, master cylinders, and brake calipers as well as replacement of the valve cover gaskets, battery, spark plugs, drive chain, and fuel tank lining. This 900SD Darmah is offered with recent service records and a clean Texas title in the seller’s name.
The fuel tank and tail section are finished in black with gold stripes over polished stainless steel fenders. The bike is equipped with a stepped two-up seat as well as both center and side stands. The tank was cleaned and lined in November 2019. Corrosion is noted on the exhaust system, headlight ears, and other brightwork. A walk-around video has been provided by the seller.
Gold six-spoke wheels were mounted with Continental tires during the 2019 work. Marzocchi suspension consists of a conventional fork and dual shocks mounted to the swingarm. The bike is equipped with dual front and single rear Brembo disc brakes. Work carried out during the recommissioning consisted of rebuilding the calipers and master cylinders, fitting stainless steel lines, and filling the system with Motul fluid.
Instrumentation consists of a US government-mandated 85-mph speedometer, a tachometer with an 8,500-rpm redline, and a five-digit odometer showing 2k miles, 300 of which have been ridden by the seller. Centrally-mounted lights indicate the status of the side stand and generator as well as the individual turn signals. The seller notes that the run switch sometimes malfunctions.
The air-cooled 864cc L-twin is mated to a five-speed transmission and features gear-driven camshafts, Dell’Orto carburetors with K&N pod air filters, Silentium mufflers, and electronic ignition. Recommissioning work carried out in November 2019 consisted of compression and leakdown tests, carburetor rebuilds, and an oil change as well as installation of a new drive chain, spark plugs, rocker cover gaskets, Yuasa battery, and Electrosport phase 2 regulator/rectifier.
