🔧 Maintenance

Oil Change Interval:

Typically every 5,000-7,500 km or annually (refer to manual for exact intervals).

Desmo Service Interval:

Desmodromic valve clearance checks and adjustments are crucial and typically recommended every 10,000-12,000 km, a significant maintenance item for Ducati owners.

Spark Plug Replacement:

Refer to manual, typically around 10,000-15,000 km.

Chain Maintenance:

Regular lubrication and adjustment (every 500-1000 km) is critical for longevity.

Brake Fluid:

DOT 4 or DOT 5.1 recommended (refer to manual for specific type and grade).

Coolant:

Ethylene glycol based coolant, typically a 50/50 mix with distilled water.

Desmo Maintenance:

The Desmodromic valve system requires precise adjustment; neglecting this can lead to performance loss or engine damage. This is a hallmark of Ducati ownership.

Electrical Gremlins:

Older Ducatis can sometimes exhibit minor electrical issues due to age and wiring loom connectors; the manual will help identify proper system operation.

Regulator Rectifier:

Some Ducati models of this era were prone to regulator/rectifier failures; while not explicitly in an owner's manual, understanding the electrical system is key.

Basic Tools:

Basic tool kit for adjustments (wrenches, sockets, screwdrivers, torque wrench).

Specialty Tools:

Specific tools for Desmodromic valve adjustment are required for that procedure, not typically user-serviceable without them.
