Overview

Introducing the 2003 Ducati ST4, a distinguished member of the sport touring category that seamlessly blends performance with comfort. As part of Ducati's celebrated ST series, the ST4 is designed for riders who crave an exhilarating experience on both the open road and winding mountain passes. With its striking Italian design and robust engineering, the ST4 stands out as a versatile machine that appeals to touring enthusiasts and sport riders alike. Whether you're embarking on a long-distance adventure or enjoying a spirited weekend ride, the ST4 offers a compelling mix of style and functionality. At the heart of the ST4 lies a powerful 916cc V2 engine, capable of producing 105 horsepower at 9,000 RPM and a hearty torque of 89 Nm at 7,500 RPM. This impressive power output translates into an exhilarating ride, providing smooth acceleration and responsive handling that will engage even the most discerning riders. The four-stroke engine, featuring a compression ratio of 11.1:1 and a 6-speed gearbox, ensures that each gear shift is precise and satisfying. Riders will appreciate the bike's liquid cooling system, which helps maintain optimal performance during extended rides. The ST4's power-to-weight ratio of 0.4884 HP/kg further enhances its dynamic capabilities, making it a joy to maneuver through twisty roads or cruise at highway speeds. Ducati has equipped the ST4 with several key features that elevate the riding experience. The sophisticated suspension system boasts 130 mm of front travel and 148 mm of rear travel, ensuring a comfortable and stable ride over a variety of terrains. Additionally, the powerful braking system, featuring double discs at the front and a single disc at the rear, offers exceptional stopping power, enhancing rider confidence. The 21-litre fuel tank provides ample range for long-distance journeys, while the adjustable seat height of 820 mm accommodates riders of varying heights, further emphasizing the ST4's user-centric design. With its combination of technology and comfort, the Ducati ST4 is truly a machine built for adventure. **

Pros

  • Powerful Engine: The 916cc V2 engine delivers an exhilarating ride with impressive horsepower and torque, perfect for both sport and touring settings.
  • Comfortable Suspension: The well-designed suspension provides excellent handling and comfort, making it suitable for long-distance rides without sacrificing performance.
  • Stylish Design: The iconic Ducati styling ensures the ST4 turns heads wherever it goes, embodying the brand’s rich heritage and Italian craftsmanship.

Cons

  • Weight: At 215 kg (474 lbs), the ST4 may feel a bit heavy for some riders, particularly in low-speed maneuvers or during stops.
  • Limited Wind Protection: While the bike is designed for sport touring, wind protection may not be as comprehensive as some competitors, leading to rider fatigue on long highway stretches.
  • Niche Market: As a sport touring motorcycle, it may not appeal to those primarily interested in either hardcore sport bikes or traditional touring machines, potentially limiting its audience.
