Ducati Monster 620 i.e. (2002-2006) Maintenance Schedule

This is the maintenance schedule and service intervals for the Ducati Monster 620 i.e., made between model years 2002 and 2006. It’s often just referred to as the Monster 620.

The Ducati Monster 620 i.e. is one of the now-established line of Ducati Monster motorcycles, middleweight street / sport bikes from Ducati powered by midrange-focused V-twin engines.

The Monster 620 is an update on the previous Ducati Monster 600. It has a slightly larger 618 cc SOHC desmodromic engine that’s still air-cooled (there’s no oil cooler) and which now has fuel injection. With a 10.5:1 compression ratio, the Monster 620 makes a modest but sporty 44 kW / 60 hp at 9500 rpm, and peak torque of 53 Nm / 39 lb-ft at 6750 rpm.

Ducati Monster 620 i.e. Service Intervals

For the fuel-injected Monster 620, service intervals are every 10000 km or 6200 miles OR every year. At every service, change the oil, check/replace the spark plugs, check the timing belt tension, and check the valve clearances.

The Monster 620 has a Desmodromic valve timing system, which means that there’s both an opener and a closer for each valve. When one gets out of spec, the other one can, too. There are only two valves per cylinder, though, so only four clearances per cylinder.

Every two services or two years (some do it every 4-5 years), you have to change the timing belts. This is a mandatory part of the service — a broken timing belt can mean bent valves, which is much more expensive service.

The Monster 620 has a hydraulic clutch, just like its bigger sibling, so make sure you keep the clutch fluid fresh, just as with the brake fluid.

What you need to service the Ducati Monster 620 i.e.

Servicing the Ducati Monster 620 i.e. is much like servicing any of the earlier air-cooled small-capacity fuel-injected V-twins.

Apart from normal motorcycle maintenance tools, here’s what you need.

Part	Ducati Monster 620 i.e. spec
Oil	The manual recommends 10W-40 engine oil for most uses. A high-quality synthetic like Mobil 1 10W-40 would be ideal.
Oil filter	The standard Ducati part 44440039A works, but the Hiflofiltro HF153RC is a drop-in replacement.
Brake fluid	Use a DOT 4 fluid, e.g. Castrol DOT 4 full synthetic.
Spark plugs	Standard type is NGK DCPR8E or a Champion RA6HC. Remember you need 4 (this is a twin spark engine).
Timing belt	Renew this before it’s too late! Part number is 73710051A. Other part numbers may fit too.
Fork oil	Use either Shell Advance Fork 7.5 or Shell Donax TA, 0.40L in each leg.
Brake pads	EBC HH pads give better bite and feel. Front: FA244HH for years 2002-2005, and then FA181HH for 2005-2006 for brakes with a single pin pad fixing caliper. Rear: FA047HH.
Air filter	Standard air filter part number is 42610111A. You can also use a K&N DU-9001.
Chain maintenance	Keep a Motul chain care kit handy to keep your chain lubricated.
Cable cleaner	Protect all cable life is a popular cable lube.
General grease	Use Lithium soap-based grease for external parts.

Regular maintenance for the Ducati Monster 620 i.e.

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

Every 1000 km/600 miles or 6 months:

Ducati Monster 620 i.e. regular maintenance
Check the engine oil level (Mobil 1 10W-40)
Check the brake and clutch fluid levels (top up with Castrol DOT 4)
Check tyre pressure and tread wear
Check the drive chain tension, alignment, and lubrication (Motul chain care kit)
Check the brake pads. Change if necessary. (Front: FA244HH / FA181HH, Rear: FA047HH.)
Check for loose fasteners, and re-torque as necessary
Lubricate control cables, and check for kinks
Check battery fluid level & charge state

About the Ducati Monster 620 i.e.

The Ducati Monster 620 i.e. continues on from the Ducati Monster 600. It’s the small-capacity Monster in Ducati’s range — but don’t let the smaller size of the engine fool you into thinking this is a low-power bike.

Rather, you’re better off thinking of the Monster 620 as an excellent everyday motorcycle. It has an under-stressed engine to the point that it doesn’t even need an oil cooler. However, some owners do add an oil cooler if they use it for a lot of spirited riding.

The core of the Monster 620 is the 618 cc L-twin. It is fuel-injected, unlike its predecessor, but still is of a single overhead cam, Desmodromic timing system, with two valves per cylinder. This means that there are four clearances per cylinder to measure and eight total.

The compression ratio of the engine is 10.5:1 — moderately high for an air-cooled engine.

The smaller Ducati Monsters always had a wet clutch and the 620 is no exception. It also has a six-speed final drive, geared for quick acceleration despite the smaller engine.

Despite being the “small” Ducati Monster, the Monster 620 has an impressive amount of kit. The inverted fork may not be adjustable, but it’s still of an inverted design with beefy 43mm stanchion tubes. At the rear there’s rebound damping and preload adjustability. And brakes are twin 300 mm discs with Brembo calipers — albeit just 2-piston types. (Note: Some spec lists list 320 mm discs, but the manual for the 620 says 300 mm.)

Ducati also released the Ducati Multistrada 620 using the same engine, but in a bike configured more to be an everyday sport tourer.

You can download Ducati manuals from Ducati here, although the one for the Monster 620 i.e. is no longer available.

Further, the Monster 620 i.e.’s manual didn’t actually have a maintenance schedule in it. There was a complicated one in the service manual, however, which is reproduced below in English.
