🔧 Maintenance

Oil And Filter Change:

Every 7,500 miles (12,000 km) or annually, whichever comes first. (Always refer to the specific service manual for exact intervals and conditions).

Desmo Service:

Desmodromic valve clearance checks and adjustments are critical and typically recommended every 7,500 miles (12,000 km) or bi-annually. This is a complex procedure requiring specialized knowledge and tools.

Major Service Intervals:

Around 15,000 miles (24,000 km) for more comprehensive checks including timing belts (if applicable to this specific generation), spark plugs, and transmission oil.

Engine Oil:

SAE 10W-40 or 15W-50 (Semi-synthetic or Full Synthetic Motorcycle Specific). Ducati recommended brands often include Shell Advance, Motul, or Castrol. Refer to the Ducati manual for the precise specification.

Brake Fluid:

DOT 4 (for both front and rear hydraulic systems).

Coolant:

N/A (Air-cooled engine)

Chain Lube:
