Ducati Monster 821 (2015-2020, all models) Maintenance Schedule

2018-2020 Ducati Monster 821-Stock Image

The Ducati Monster 821 maintenance schedule and service intervals — sourced from the owner’s manual.

This applies to these models: the 2015, 2016, 2017, 2018, 2019 and 2020 Ducati Monster 821. It also applies to the Monster 821 Stripe, Monster 821 Stealth, and the Monster 821 Dark, which only had cosmetic differences.

The Monster 821 was released in 2015 to replace the earlier 796. It has the same 821 Testastretta engine that was in the Hypermotard of earlier years. It’s a great engine — but in terms of maintenance, the most important thing is that it has a wide (for Ducati) 18,000 mile or 30,000 km valve inspection interval. Considering that there are now four valves per cylinder as standard, this is a huge blessing!

The Monster 821 also has five-year belt replacement intervals, another large improvement over earlier manuals which required 2-year replacements (though most owners do it between four and five years anyway).

In 2021, the Monster 2021 was replaced with the new Ducati Monster and Monster+, which some refer to as the Monster 937 or Monster 950.

What you need to maintain the Ducati Monster 821

Aside from general motorcycle maintenance tools, the following is a list of consumables (things like oil, spark plugs etc.) you need to maintain the Ducati Monster 821.

OilDucati recommends Shell Advance Ultra 15W-50 motorcycle oil, or another high-quality synthetic motorcycle oil like Motul 7100 15W-50 or Mobil 1 Synthetic 15W-50.
Oil filterGenuine Ducati part is 44440037A. I’d suggest removing that and using a HifloFiltro HF153RC oil filter which can be changed with a normal wrench.
Brake fluid, Clutch fluidDucati recommends Shell Advance DOT 4, but that’s quite hard to find, so Castrol DOT 4 Synthetic is a good and very high-quality alternative.
CoolantDucati recommends Shell Advance Coolant or a 35-40% mix of Glycoshell, a low-silicate, and nitrite-, amine-, and phosphate-free coolant. Motorex M3.0 is a suitable alternative.
Timing beltIs it time to change the timing belt? Don’t put it off… a broken timing belt will cost you a lot! You need part number 73740252A (and you need two).
Front brake padsStandard brake pads code is 61341021A. You can also use EBC FA630HH for more bite/feel.
Rear brake padsUse original part number 61340951A, EBC part number FA266HH for more bite/feel (and availability online)
Spark plugsNGK code MAR9A-J. Note they’re sold individually (and you have two cylinders).
Air filterThe part number for the air filter is 42610191A. You can also use K&N DU-1006.
Consumables for Ducati 821 series engines (Monster, Hyper)

You may also need the following general consumables to maintain your Monster 821.

motorcycle maintenance tools - paddock standPaddock Stand — Makes maintaining your chain or doing other maintenance much easier.
motorcycle maintenance tools - motul chain pasteMotul chain paste — one of the most highly-regarded chain lubes. Easy to apply, doesn’t fling off. If you need more stuff, get the Motul chain care kit as an affordable package.
Valvoline full synthetic lithium soap-based greaseAlways good to have on hand lithium soap-based grease for lubing external pivot points (like the swingarm) and bearings.
motorcycle maintenance - cable lubricantUse Protect all cable life to lubricate your cables and controls.

Regular maintenance for the Ducati Monster 821

This is maintenance that you can do yourself (though the manual says you need a dealer to do it).

Using the motorcycle under extreme conditions, such as very damp and muddy roads or dusty and dry environment, could cause above-average wear of components like the drive system, the brakes or the air filter. If the air filter is dirty, the engine could get damaged. So replace/maintain those more often if you put them under duress.

Every 1000 km/600 miles miles OR 6 months (whichever comes earlier, perform the following maintenance:

Check engine oil level (top up with Shell Advance Ultra if required)
Check brake fluid level (Castrol DOT 4)
Check tyre pressure and wear
Check the drive chain tension and lubrication (lubricate with Motul chain paste)
Check brake pads, replacing if necessary (front: 2x EBC FA630HH, rear: EBC FA266HH)

General Information on the Ducati Monster 821

The Ducati Monster 821 was a huge tech update on early Ducati Monsters, as well as an aesthetic resign.

At its core, the Ducati Monster 821 is still the same bike it has always been — a middleweight naked sportbike that isn’t as aggressive as the Streetfighter range, but not as docile as for example a Triumph Bonneville.

For those who want a little more aggression, the Monster 821 had a big brother, the Ducati Monster 1200, which got a lot more power, tech, and some more weight.

In 2018, Ducati revised the Monster 821 somewhat, with a new tank, tail section, headlight, and muffler. The intention was to make it more “classic” looking, like the original Monster 900.

The engine however stayed the same, as did the basic maintenance.

In 2021, the Monster 821 was replaced with a motorcycle simply known as the Ducati Monster. It shares its 937cc engine with motorcycles like the Ducati Supersport.
