In 2000, the Italian motorcycle manufacturer launched the Ducati ST4, a sport-touring motorcycle that debuted in 1999 and was manufactured until 2005. The bike used a retuned version of the engine that powered the Ducati 916 model.
The ST4 was part of the ST series that comprised five motorcycles with different engines. In contrast, all ST machines shared the same frame, Bodywork, and cycle parts. Also, the numbers in the name indicated how many valves were per cylinder.
In the appearance department, the bike was equipped with standard features such as a full fairing, an adjustable windscreen, integrated front turn signals, a one-piece dual seat with a passenger grab handle, a dual exhaust system, and three-spoke lightweight aluminum wheels.
In the suspension department, the bike packed a 43 mm fully adjustable upside-down Showa telescopic fork on the front and a fully adjustable Sachs shock absorber with progressive linkage on the rear.
As for the braking power, the bike's wheels were fitted with two 320 mm discs and four-piston calipers on the front and a 245 mm disc with a dual-piston caliper on the rear wheel, delivering reliable stopping performance.
The 2000 Ducati ST4 packed a 916cc four-stroke liquid-cooled V-twin engine fed by an Electronic Fuel Injection (EFI) system, delivering an output power of 105 hp with a peak at 9,000 rpm and 89 Nm (66 lb-ft) torque at 7,500 rpm.
