Pros and Cons in comparison

Ducati Monster 821 2017

Ducati Monster 821 2017

The Ducati Monster 821 fits perfectly into the gap between the entry-level Monster 797 and the top-of-the-range Monster 1200. The Monster 821, with its many electronic gadgets such as adjustable ABS, adjustable traction control, riding modes and colour TFT display, is more in line with the 1200 models. The typical V2 engine with desmodromic works powerfully but also very harmoniously, the chassis lacks adjustment options, especially on the fork, but the comfortable compromise can still be seen and felt. Visually, there is nothing to criticise anyway, the Monster 821 is also clearly recognisable as a Monster and, above all, in the yellow paintwork, a worthy model for the 25th anniversary of Monster.
