The Ducati Monster 821 is a discontinued 821 cc air-cooled motorcycle with a 6-speed gearbox. UltimateSpecs lists 109 HP @ 9250 rpm maximum power, 86 Nm @ 7750 rpm maximum torque, Brembo M4-32 4-piston double-disc front / single-disc rear brakes with ABS, a 120/70-ZR17 front and 180/55-ZR17 rear tyre, a 17.5 litre fuel tank and a 195 kg kerb weight.
The Ducati Monster 821 is a motorcycle from Ducati. It was launched in 2018 and has since been discontinued. Mechiee still services it at your doorstep. With a 821 cc engine it sits in the big-bike, 800 cc-plus class.
Power comes from a 821 cc air-cooled fuel-injected engine that makes 109 HP at 9,250 rpm and 86 Nm of torque at 7,750 rpm. Its bore is wider than its stroke (88.0 x 67.5 mm), a short-stroke layout that generally favours higher revs. Divide power by kerb weight and it has about 567 PS per tonne; by that measure, its performance is at superbike level and rewards an experienced rider. It has electric start.
It has a 6-speed manual gearbox, and a chain carries drive to the rear wheel. Its slipper clutch lightens the lever and stops the rear wheel hopping when you downshift hard.
It is built around a tubular steel trellis frame attached to the cylinder head frame. At the front, the suspension is 43mm upside-down forks. At the rear, it is progressive linkage, adjustable monoshock, aluminium double-sided swingarm. Braking is by twin 320 mm discs at the front and a 245 mm disc at the rear. It rides on 17-inch wheels — 120/70-ZR17 at the front and 180/55-ZR17 at the rear.
The seat is 785 mm off the ground, which is about average and suits most riders. It weighs 195 kg ready to ride, which is on the heavy side, so moving it by hand takes some effort. It is 2,170 mm long, with 1,480 mm between the axles. It carries 17.5 L of fuel.
For the Ducati Monster 821, Mechiee offers a fixed ₹17,999 doorstep service.
Its low seat also makes it approachable for shorter and newer riders. With this much performance, it is better as a step-up bike than a first bike.
Its chain drive needs regular cleaning, lubrication and slack adjustment.

Mechiee doorstep service
₹17,999
Mechiee's fixed doorstep service price for this model.
Follow the schedule in the owner's manual for your exact variant and year. A regular service is the cheapest way to catch small problems before they become expensive ones.
Engine oil is the single most important consumable to keep fresh. Top up between services if the level drops, and change it on schedule.
With Double disc, 320 mm, Brembo M4-32 4-piston Monobloc, ABS and Single disc, 245 mm, 2-piston floating, ABS brakes, check pad or shoe wear, lever and pedal free play, and braking feel at every service.
A clean, correctly tensioned and lubricated chain lasts longer and wastes less power. Check slack regularly, especially after riding in rain or dust.
A liquid-cooled engine relies on coolant. Check the level and look over hoses and the radiator for leaks or damage, and replace coolant as the owner's manual directs.
A clogged air filter or worn spark plug shows up as hard starting, weak throttle response and poorer fuel economy. Both are checked at a regular service and replaced when worn.
Brake fluid absorbs moisture over time, which lowers its boiling point. Have its level and condition checked and change it on the interval in the owner's manual.
This bike runs 120/70-ZR17 / 180/55-ZR17 tyres. Check pressure, tread depth and sidewalls, and replace tyres that are worn or cracked.
Weak starting, dim lights or a flickering console are early signs the battery or charging system needs a look.
