A bold and essential form shaped by a unique history, combined with the unmistakable Ducati roar released from the 112hp Testastretta 11° engine, are hallmarks of the Monster 821. Trellis frame, Riding Modes, and the Ducati Safety Pack are the elements that bring you unprecedented riding pleasure. Monster 821. Designed according to your desires, to be even more Monster

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.

Thanks to the specially designed air filter and exhaust system, the Testastretta 11° engine generates power comparable to that of a 3/4 cylinder engine. Even the most demanding "Monsteristi" and sports riders will be able to appreciate the punchy torque that is readily available at a wide range of speeds, already reaching more than 85% of its maximum torque at 5500 rpm. The Testastretta 11°'s character is enhanced by the choice of the final ratio set to develop maximum acceleration in each gear and maximum engine response with each turn of the throttle.

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 Testastretta 11° 821 engine is combined with a type 2-1-2 exhaust system, which leaves no room for doubt about the performance that the new Monster 821 is capable of unleashing. The engine control unit has a lambda probe for each individual cylinder, guaranteeing delivery of the right amount of fuel, while the stylish vertically stacked cannon silencers are equipped with catalytic converters that ensure compliance with Euro 3 standards. An electronically controlled mid-section adjustment valve optimises exhaust pressure according to engine speed.

The front brakes of the Monster 821 have high-performance, pump-activated Brembo monobloc M4-32 radial callipers, equipped with high-calibration multiple 9MP ABS as standard. The four-piston front callipers, fitted radially, act on 320 mm discs, while the Brembo two-piston rear calliper is fitted on a 240 mm disc.

The geometry of the frame, inspired by racing bikes, is completed by inverted forks (Ø 43 mm), while the rear suspension is entrusted to a Sachs monoshock with adjustable compression and extension, mounted on one side vertically on the cylinder head and, on the other, on a sturdy Ducati double-sided swingarm. This exceptional suspension allows contact with the wheel to be maintained and guarantees control and agility even in extreme driving conditions.
