Horsepower 620:
Estimated 50-60 HP (specific figures detailed in manual)
Torque 620:
Estimated 35-45 lb-ft (specific figures detailed in manual)
Induction 400:
Likely Carbureted (Mikuni or Keihin twin carbs typical for this size)
Induction 620:
Likely Fuel Injection (EFI) for this displacement, or potentially later carb models. Manual will clarify.

Safety Compliance:
European (EU) and North American (NA) safety standards relevant to motorcycle production of the era. Specific certifications not detailed in product info.
Braking System:
Hydraulic Disc Brakes (front and rear, specific caliper and rotor sizes detailed in manual). ABS was not standard on these models.
Lighting System:
Standard motorcycle lighting (headlight, taillight, turn signals). Wiring diagrams and bulb types are in the manual.
Dashboard Features:
Analog tachometer, digital speedometer, odometer, trip meter, warning lights (specifics and calibration in manual).
ABS Availability:
Not typically standard on these model years, but manual might cover optional ABS systems if applicable.
Diagnostic Ports:
Likely includes a diagnostic connector for electronic fault code reading (specific type and location in manual).
Oil Change Interval:
Typical interval around 6,000-8,000 km or annually (specifics in manual)
Valve Check Interval:
Crucial for Desmodromic engines; typically 10,000-12,000 km (detailed procedure and specs in manual)
Timing Belt Replacement:
Critical maintenance item for Ducati L-twins, typically every 2 years or a specific mileage (e.g., 10,000-12,000 km) - detailed in manual
Brake Fluid Type:
DOT 4 (specific grade and replacement interval in manual)
Clutch Fluid Type:
DOT 4 (if hydraulic clutch, specific grade and replacement interval in manual)
Common Concerns:
Timing belt wear/failure (critical preventative maintenance), electrical gremlins (common in older bikes, manual helps diagnose), clutch slave cylinder leaks, potential fueling issues with age.
Preventative Maintenance Importance:
Adherence to schedule, especially timing belts and valve adjustments, is paramount for longevity and preventing catastrophic engine failure.
