25 years of Monster

The Monster 821 has been upgraded to include aesthetic and functional features first introduced on the Monster 1200: a more streamlined, agile look with fully redesigned tank and tail, an all-new silencer and a headlight that is both classic and contemporary. Also making its debut on the mid-size Monster is the colour TFT display with selected gear and fuel indicators, while available accessories include the Ducati Quick Shift up/down system.

The Monster 821 also features the Ducati Safety Pack, which comprises Bosch ABS and Ducati Traction Control, both of which have adjustable intervention levels. Similarly, maximum power and throttle response can be adjusted via the Power Modes. Riding Modes allow easy adjustment of ABS, DTC and Power Modes, letting riders transform the 821 into three different motorcycles, each with a distinct personality.

Completing the impressive equipment array on the Monster 821 are the Brembo brakes, with dual 320 mm discs and M4-32 monobloc radial calipers up front. A refined suspension system includes a 43 mm fork at the front and an adjustable shock absorber at the rear.

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. The Monster 821 is also available for those with a restricted licence, as a version with 35 kW of regulated power.

The pleasure of a safe ride

In perfect harmony with the road, the new Monster 821 is capable of conveying pleasant riding sensations, supported by advanced technology and the specially designed ergonomics of this model.

Endless excitement

The advanced materials and technologies of the Ducati Testastretta 11° engine allow for particularly long maintenance intervals and reduced running costs, calling for an oil change every 15,000 Km (or 12 months) and valve clearance control (Desmo Service) every 30,000 km.
