MONSTER 821/ MONSTER 821 STEALTH
That's why #welovemonster
25 years of Monster
The Monster 821 pays homage to the legacy of the Monster 900, which over 25 years ago revolutionised the motorcycle world. Agile and featuring sporty performance, it was designed for maximum riding enjoyment, at all times and in all conditions. The Monster 821 range has been rejuvenated with a new stealth version: matte black livery, updated graphics and front fairing give a unique character to the naked Ducati par excellence. The standard equipment, which includes adjustable fork and Ducati Quick Shift up/down, makes it even more effective on the road.

Iconic design
![]()
The volumes, silhouette, tank and headlight characterise the design of the Monster 821 and remain true to the original lines of the bike born in 1993 while revisiting them with a modern flair. The iconic tank comes with a fastening hook, just like the first Monster. The new stealth version features new graphics and the windshield: elements that give the new Monster 821 a unique and unmistakable character. -
Testastretta 11° engine

Thanks to high maximum power and torque values, fluid delivery and a full torque curve at all speeds, the new Monster 821's Testastretta 11° engine can guarantee performance and agility to the rider.
