Ducati Monster S4R Testastretta Review: The Ultimate Naked Performance Machine
The Ducati Monster S4R Testastretta is a beast that perfectly blends raw power with a stripped-down, aggressive design. Introduced as one of the most performance-driven naked bikes in Ducati’s Monster lineup, the S4R Testastretta borrows its soul from Ducati’s superbike heritage. With a powerful engine, premium components, and a chassis designed for precision handling, this machine remains a coveted choice for riders who crave a thrilling ride without sacrificing everyday usability.
Design & Aesthetics
Ducati’s design philosophy for the Monster S4R Testastretta is simple—bold, muscular, and unapologetically aggressive. The bike’s trellis frame, exposed engine, and single-sided swingarm create a visually stunning profile.
Ducati Monster S4R Testastretta: The Epitome of Naked Performance
Available in signature Ducati red, black, and white, the Monster S4R Testastretta commands attention wherever it goes. The twin high-mounted exhausts give it an unmistakable racing appeal, while the premium carbon fiber accents enhance both aesthetics and performance.

Technology & Features
While the S4R Testastretta is a raw performance machine, it doesn’t skimp on technology. It features a fully digital instrument cluster providing essential ride data, while high-performance Öhlins suspension components offer superior ride quality and adjustability. Although it lacks modern electronics like traction control or multiple ride modes, its lightweight frame and high-end Brembo braking system compensate by offering pure mechanical grip and stopping power.
Comfort & Ergonomics
The Monster S4R Testastretta strikes a balance between aggressive sport riding and everyday comfort. The slightly forward-leaning riding position enhances control while ensuring comfort for longer rides. The well-padded seat and adjustable suspension make it capable of handling both spirited rides and daily commuting. However, taller riders may find the compact ergonomics a bit cramped over extended distances.
Braking & Safety
Ducati equips the S4R Testastretta with top-tier Brembo brakes—a dual-disc setup at the front and a single-disc at the rear. These brakes provide exceptional stopping power, ensuring confidence in high-speed situations. While it lacks ABS, experienced riders will appreciate the direct and responsive braking feel that adds to the overall riding thrill.
Fuel Efficiency & Maintenance
With an average fuel consumption of around 35-40 mpg, the S4R Testastretta is reasonably efficient for its class. However, Ducati’s high-performance engines require regular maintenance, including valve adjustments and belt replacements. While maintenance costs may be higher than those of Japanese rivals, the trade-off is a machine that offers an unmatched riding experience.
Comparison & Competitors
The Ducati Monster S4R Testastretta competes with the Triumph Speed Triple, Aprilia Tuono, and KTM 990 Super Duke. While the Speed Triple offers a more refined ride and the Tuono boasts advanced electronics, the Monster S4R Testastretta stands out with its raw, race-inspired performance and unique Italian styling. It’s an excellent choice for riders who value character, power, and exclusivity over electronic rider aids.
Engine & Performance

At the heart of the S4R Testastretta lies a 998cc L-twin Testastretta engine, producing an exhilarating 130 horsepower and 103 Nm of torque. This naked monster borrows its engine from the Ducati 999 superbike, ensuring explosive acceleration and high-revving performance.
