Tools you may need to maintain your motorcycle
To maintain your motorcycle you need to make sure you have the best oil and other consumables, motorcycle-specific tools, and other tools for your workshop.
Below we’ve listed:
- The most essential motorcycle tools for everyday maintenance
- General workshop tools (sockets, pliers, wrenches etc.) for motorcycles and other use
What you need to maintain the Ducati Monster 821
The following is a list of consumables (things like oil, spark plugs etc.) you need to maintain the Ducati Monster 821.
|Oil||Ducati recommends Shell Advance Ultra motorcycle oil. You need 3.7L for a complete oil change. It’s hard to find and expensive so people suggest Mobil 1 Synthetic. A lot of Ducati owners use Shell Rotella T4 for everything from street use to racing.|
|Oil filter||Genuine Ducati part is 44440037A. I’d suggest removing that and using a K&N KN-153 oil filter which can be changed with a normal wrench.|
|Brake fluid, Clutch fluid||Ducati 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.|
|Coolant||Ducati recommends Shell Advance Coolant or a 35-40% mix of Glycoshell, a Nitrite, Amine, and Phosphate-free coolant. This is quite hard to find. But any ethylene glycol-based coolant will do the job.|
|Timing belt||Is 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 pads||Standard brake pads code is 61341021A. You can also use EBC FA630HH for more bite/feel.|
|Rear brake pads||Use original part number 61340951A, EBC part number FA266HH for more bite/feel (and availability online)|
|Spark plugs||NGK code MAR9A-J. Note they’re sold individually (and you have two cylinders).|
|Air filter||The part number for the air filter is 42610191A. You can also use K&N DU-1006.|
You may also need the following general consumables to maintain your Monster 821.
|Chain lubricant||The chain needs to be lubricated every 800 km/500 miles (or more, if it gets wet/dirty). Motul chain paste is cheap and well-loved.|
|Chain cleaner brush||A chain cleaner brush makes cleaning off grime and then distributing new lubricant much more easy.|
|Paddock stand||Lubricating the chain and changing the oil both become a lot easier once you use an affordable paddock stand.|
|Cable lubricant||Remember to lubricate your clutch cable (and brake cables if you have them) with a cable lubricant. Protect All Cable Life is a good general-purpose lubricant.|
|Grease||Get a good lithium soap based grease for lubricating major components like your side stand, centre stand, and bearings.|
Regular maintenance for the 2018-2020 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. Therefore, this might translate in required service or replacement of the wear parts earlier than specified in the scheduled maintenance chart.
Every 1000 km/600 miles miles OR 6 months (whichever comes earlier, perform the following maintenance:
|Check engine oil level|
|Check brake fluid level|
|Check tyre pressure and wear|
|Check the drive chain tension and lubrication|
|Check brake pads. If necessary, contact your dealer to replace pads|

General Information on the 2018-2020 Ducati Monster 821
Newly revised in 2018, the Monster 821 from Ducati benefits from some trickle-down engineering from its big brother, the Monster 1200, and a host of new design touches all its own. A new tank, tail section, headlight and muffler gives it an all-new variation on the classic Monster look with due consideration for the original Monster 900.
Duc’s Testastretta L-twin powerplant serves up streetfighter performance with 109 horsepower tucked away in the stable and a host of safety systems to aid the rider in keeping it all under control.
