Ducati Monster 821 – That’s why #welovemonster
The Monster 821 pays homage to the legacy of the Monster 900, which over 25 years ago revolutionised the motorcycle world which set the benchmark for all naked sports bikes.
The design of the new Monster 821 are true to the original lines of the bike born in 1993 but revisited with a modern flair. The silhouette and unmistakable tank also comes with a fastening hook, just like the first Monster.
With its sporty performance and agility, the new Monster 821 has been designed for maximum riding pleasure. The performance of the 109 HP Testastretta 11° engine is enhanced by the Ducati Safety Pack (ABS and Ducati Traction Control) and the Riding Modes (sport, touring, urban), which guarantee maximum safety always and everywhere.
In 2018, the Ducati Monster 821 has been sharpened to follow the lines of its three bigger brothers the Monster 1200, 1200S and the Monster 1200R
The Monster 821 is also available for those with a restricted A2 licence, as a version with 35 kW of regulated power.
The low maintenance Ducati Testastretta 11° engine of the Monster 821 allow for particularly long maintenance intervals and reduced running costs, with oil changes every 9,000 miles (or 12 months) and valve clearance and belt change (Desmo Service) every 18,000 miles.

The Monster 821 Engine
The Monster 821 is powered by the Testastretta 11° 821 cc engine, with air injection system. A secondary air system similar to the one used on the 1199 Panigale has been introduced in order to optimise operation and reduce combustion cycle variability, without affecting emissions. A controlled flow of clean air is injected into the exhaust pipe, enabling total oxidation of the hot exhaust gases, efficiently cutting hydrocarbon and carbon monoxide levels.
The Testastretta 11° engine fitted to the Monster 821 is an exclusive feature of these bikes and its structure has been engineered to be an integral element of the frame. In addition, the air filter and exhaust system have been designed to provide improved torque at low-medium engine speeds.
The transmission features an oil bath clutch with “slipper” function and a lever that is very light to the touch. It is equipped with a gradual self-servo system that compresses the discs when the engine speed is reduced, allowing the load on the pressure plate springs to be reduced. This reduces the stress on the clutch lever, ensuring optimum conditions in city traffic when frequent gear changes are required, or on long trips.
When the transmission force is reversed (overload), the same mechanism makes it possible to reduce the pressure on the clutch plates, enabling them to work in “slipper” mode, which reduces the destabilising effect on the rear end during aggressive downshifting and gives a feeling of greater fluidity when decelerating or downshifting in normal driving conditions.
The meticulous design and top-quality materials used for the Monster have allowed amazing results to be achieved.
Adjusting the valve clearance is scheduled for every 30,000 km and changing the oil every 15,000 km, increasing service intervals and cutting running costs. These results were made possible by improving combustion efficiency and cutting the operating temperatures of the Testastretta 11° engine.
The Monster 821 now comes with a TFT display
The new Monster 821 is fitted with an adjustable seat (± 25 mm) that can adapt to the needs of customers all over the world.
The standard seat height can easily be adjusted to the lowest (785 mm) or highest (810 mm) positions. In addition, two optional seats allow riders to lower it another 20 mm (765/790 mm) or even 40 mm (745/770 mm).
