Ducati Monster 821
The Ducati Monster 821 has a top speed of 230 km/h (estimated), produces 109 hp and weighs 193 kg. Motoryk rates it 8/10.
La Ducati Monster 821 a été présentée en 2014 en tant que roadster nu de milieu de gamme, se situant entre le Monster 696 et le produit phare Monster 1200 pour élargir l'attrait de la gamme Monster. Elle était équipée du moteur bicylindre Testastretta 11° et se distinguait par le fait qu'elle offrait une expérience plus haut de gamme et axée sur les performances aux pilotes qui recherchaient plus qu'un Monster d'entrée de gamme sans l'engagement total de la 1200. Le 821 a reçu des mises à jour en 2018 avec un style révisé et une électronique améliorée avant d'être abandonné vers 2021, remplacé par le Monster 937.

Ce que les acheteurs doivent savoir
Desmo Service Costs
The Ducati Monster 821 requires a Desmodromic valve service every 15,000 miles, which can cost $600–$1,200 at a dealership. Always verify service history before buying, as skipped intervals can lead to serious engine damage.
Watch for Coolant Leaks
A known issue on the 821 is coolant weeping from the water pump seal, especially on pre-2018 models. Inspect the lower left engine area carefully and ask the seller about any overheating history.
Strong Resale Value
The Monster 821 holds its value better than many middleweight competitors, often retaining 60–70% of its original price after three years. Its Ducati badge, sporty styling, and liquid-cooled 821cc twin make it consistently desirable on the used market.

Évaluation d'un acheteur d'occasion
"A brilliant middleweight if bought with eyes wide open."
$7,500-$11,000 usedThe Monster 821 sits in that sweet spot where Ducati character meets everyday usability, but buying one used requires homework. The 821cc Testastretta twin pulls hard from 4,000rpm and sounds absolutely savage with a decent exhaust, but check the service history religiously — desmo valve services run $600-1,000 and many previous owners conveniently 'forgot' them. Look for bikes with documented 15,000-mile services and ask specifically about the belt change history. The riding position is genuinely comfortable for a naked bike, and the chassis feels telepathic through corners. DTC traction control and ABS are confidence-inspiring without being intrusive. Earlier 2014-2015 examples had some fueling hiccups at low speeds that Ducati improved in later models, so 2017-onward bikes are noticeably smoother in traffic. Seat quality is questionable beyond 90 minutes, and Italian electrics can surprise you if the bike sat unused. Budget an extra $1,500 above purchase price for a full service and peace of mind. Do that, and you've got one of the most rewarding middleweights available.
