The Ducati Monster 821 Stealth Is Back For Another Year
Contents
Similar to the Monster 821, the Monster 821 Stealth returns to the 2021 Ducati line-up for North America. With Euro5 regulations in place, this model is no longer available in Europe but will still be on sale in the United States and Canada for the moment. It’s not the only older Ducati motorcycle to soldier on for another year, but it’s probably the most aesthetically pleasing.
Designed as a more exclusive version of the standard Monster 821, the 821 Stealth is almost identical to the base model, though there are some key differences. The engine isn’t one of them. The Stealth model uses the same Italian-made 821cc Testastretta twin-cylinder engine, producing the same 109 horsepower and 63 lb-ft of torque. Other equipment also remains the same, including the adjustable front forks, Ducati electronics package, and Ducati’s own quick-shift technology.
The main difference is an exclusive “Stealth” livery with updated graphics and the addition of a small but effective front screen that gives the Monster 821 stealth a unique character.
For 2021, the new Monster 821 Stealth is available exclusively in a black “Stealth” color option, with light grey and red accents.
The 2021 Ducati Monster 821 Stealth starts at $12,895 USD / $14,295 CAD.
