The 2006 Monster S4RS Testastretta was valued for its clean looks and its race-quality Ohlins suspension package.

The Monster S4RS Tricolore was a special edition bike that was destined to become a collectible from the moment of its release to the general public. This naked road bike stole the show with its vibrant Italian color scheme. It was further enhanced with accents of gold finish on the front fork, the exhaust, the frame, and on the wheels. This made it one of the most beautiful Monsters from an aesthetics standpoint. This exceptionally exciting Monster featured all of the racing capabilities and features of the S4RS Testastretta. It was equipped with a four-stroke, liquid-cooled, DOHC, desmodromic 4 valves per cylinder, 90-degree V-Twin Testastretta 998 cc engine. The horsepower and torque remained the same with no changes. The motor was paired with a 6-speed manual gearbox with a dry multiplate hydraulic control clutch. The fuel capacity of the tank was a mere 4 gallons, which could have been improved upon, but it would have added to the size and weight.

The more prolific 2008 Ducati Monster S4RS Testastretta was the less flamboyant edition that didn't offer the special graphics and colors of the Tricolore, but it was the same bike less the fanfare. This was a popular model within the Monster lineup with agile handling and dual capabilities for racing on the track or dirt trail biking or taking down the highway for touring. The naked road bike remained pared down to a slender weight in its final year of production before being replaced by its successor. As with the Tricolore, the S4RS Testastretta is equipped with the racing-grade Ohlins suspension package, a Brembo braking system, a micro-fairing with a small windscreen for rider and passenger comfort.


The Ducati Monster S4R became an important model within the Monster family. It provided riders with the option of a larger bike within the dual-purpose racing and street-legal category. Riders thoroughly enjoyed the comforts of a touring motorcycle featuring agility around corners, stability, and a smooth ride. There weren't many variants of the Monster S4R produced. The production run, for some, was too short in duration. The decision to cease production left enthusiasts wondering why the Monster SR line came to an end. As with all good things, the Ducati Monster S4R had served its purpose. The powers that be knew it was time to move the S4R aside and make room for the new generation of naked road bikes. Ducati likes to change things up and keep it interesting with innovations and automotive technology. The Monster line infused new life into Ducati. It's the line that sparked a renewed interest in the brand that endures to this day. It's wise to maintain a progressive line with continual improvements. Ducati understands this necessity as the brand continues to move forward. Each new model leaves an impression of what works and what needs improvement. The S4R wasn't a perfect motorcycle, but it filled an important place in the naked road bike segment.
