DUCATI250 Diana 1961 - 1964

　　The Ducati Diana, also known as the Ducati Daytona in the British market, was a sports motorcycle powered by a 249cc single-cylinder Bevel drive SOHC engine, manufactured between 1961 and 1964.

　　It was the sports-oriented version of the Ducati's first 250cc road motorcycle. It was replaced in 1964 by the high-performance Ducati Diana Mark 3 in the American market and by the Ducati Mach 1 in 1964 in the European market.

　　In addition, the Diana model was available with a race kit comprising a high-compression 9:1 piston, a 27 mm Dell'Orto SS1 carburetor, and a megaphone silencer. In a road test conducted by Motorcycle Magazine, the 250 Diana reached a top speed of 160 kph (100 mph) with the race kit installed.

　　In 1961, the Italian motorcycle manufacturer launched the Ducati 250 Diana, a sports motorcycle fitted with a large, round headlight up front, a large fuel tank, a low handlebar, a single seat, a center stand, and wire-spoke wheels.

　　Underneath its fuel tank, the 1961 Ducati 250 Diana had installed a 249cc four-stroke single-cylinder air-cooled engine with a Dell'Orto carburetor, delivering 19.5 hp with a peak force at 7,550 rpm.

　　As for the braking power, the bike packed a 180 mm drum braking unit on the front wheel and a 160 mm drum braking unit on the rear wheel, offering optimum stopping performance.
