2021 Ducati Streetfighter V4 S Technical Analysis & Specification Breakdown
Positioned in Ducati's naked motorcycle lineup, the 2021 Ducati Streetfighter V4 S pairs a 1103 cc (67.3 cu in) liquid-cooled v4, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 208 HP (151.8 kW) at 12,750 rpm while maximum torque reaches 123 Nm (90.7 lb-ft) at 11,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 188.6 HP per liter and a 1,250 rpm working window between peak torque (11,500 rpm) and peak power (12,750 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Streetfighter V4 S measures 201 kg (443 lbs) wet (curb), translating to a power-to-weight ratio of 1.03 HP/kg (0.97 kg per horsepower). Rider ergonomics and chassis geometry center around a 845 mm (33.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,488 mm (58.6 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank paired with a rated consumption of 7.6 L/100 km provides an estimated theoretical range of roughly 211 km (131 miles) between fill-ups.
