DUCATI Monster S4 (2001-2002) Specs, Performance & Photos

The Monster family was a range of standard or naked machines designed by Miguel Angel Galluzzi and manufactured since 1993. The Monster was built in Bologna, Italy, and over the years, the family comprised numerous variations with similar appearances and different engine displacements.

In the 2001 Ducati line-up were several motorcycles, including the Ducati Monster S4, a naked machine that introduced a liquid-cooled four-vale per cylinder Superbike engine along with other technical modifications, such as semi-floating disc brakes engaged by Brembo four-piston calipers, lighter Brembo wheels, and a 43 mm inverted Showa fork on the front.

In the appearance department, the 2001 Ducati Monster S4 packed a round headlight with a small fairing and windscreen, a single seat, the signature style tubular steel Trellis frame, an upswept exhaust system, and five-spoke lightweight aluminum wheels.

In the power department, the bike took its muscles from a 916cc four-stroke liquid-cooled V-twin engine with an electronically controlled fuel injection system in charge, delivering an output power of 101 hp with a peak force at 8,750 rpm and 92 Nm (68 lb-ft) torque at 7,000 rpm.

The power was handled by a six-speed manual transmission with a hydraulically controlled dry multi-place clutch and a final chain drive, pushing the machine to 239 kph (149 mph).

The lightweight aluminum wheels were fitted with two 320 mm semi-floating discs with four-piston calipers on the front and a 245 mm disc with a dual-piston caliper on the rear, offering strong stopping power.
