Vehicle Information
Ducati Monster 821 Motorcycle - Street (2015-2021)
The Ducati Monster 821, produced from 2015 to 2021, is a naked sportbike renowned for its accessible performance and iconic design. Powered by an 821cc Testastretta 11° L-twin engine, it offered a thrilling ride with varying horsepower outputs: 112 hp from 2015-2017, and 109 hp from 2018-2021 due to Euro4 compliance. Trims included the Standard, the matte black Dark, the distinctive Stripe with its red frame and white stripes, and the Stealth, featuring a matt black livery, quick shifter, and adjustable fork. A significant refresh occurred in 2018, introducing a new color TFT dash, updated bodywork resembling the Monster 1200, and Euro4 emissions compliance. While the 2021 Monster 821 in North America was a carry-over of the 2020 model, the 821 series was effectively replaced in other markets by a new Monster with a 937cc engine and a new chassis. This 2018 update represents the primary generation break within the 821's production run. FAQ:
