Bore X Stroke:
98 mm x 71.5 mm
Compression Ratio:
12.4:1
Valvetrain:
Desmodromic, 2 valves per cylinder, pushrod actuated (not common Ducati V-twin, this is incorrect, it's desmo with cams)
Valvetrain Correction:

Horsepower Claimed Peak:
Approx. 98 hp (72 kW) @ 7500 rpm
Torque Claimed Peak:
Approx. 105 Nm (77.4 lb-ft) @ 4750 rpm
Fuel Delivery:
Marellli Electronic Fuel Injection (EFI), single 50mm throttle body
Fuel Type:
Unleaded Gasoline (95 RON or higher recommended)
Oil Capacity:
Approx. 3.5 Liters (3.7 US qt)
Oil Type Recommendation:
Refer to manual for specific viscosity grade (e.g., 15W-50 or 20W-50 synthetic)
Oil Filter Change:
Every 12,000 km (7,500 miles) or 12 months, whichever comes first.
Desmo Service:
Every 24,000 km (15,000 miles) - crucial for valve adjustment and inspection of Desmodromic system.
Spark Plug Replacement:
Every 12,000 km (7,500 miles).
Air Filter Cleaning Replacement:
Inspect every 12,000 km (7,500 miles); replace as needed or at 24,000 km (15,000 miles).
Chain Inspection Lubrication:
Every 1,000 km (600 miles) or after washing/rain.
Brake Fluid Flush:
Every 24,000 km (15,000 miles) or 24 months.
Engine Oil Specification:
Refer to Ducati manual, typically SAE 15W-50 or 20W-50 fully synthetic motorcycle oil meeting API SG/SH/SJ/SL or higher, and JASO MA specification.
Brake Fluid Specification:
DOT 4.
Coolant Specification:
N/A (Air-cooled engine)
Clutch Fluid Specification:
DOT 4 (shared with brake system).
Clutch Slave Cylinder:
Some owners report occasional issues with the clutch slave cylinder seal, leading to slight clutch fluid leaks. Aftermarket upgrades are available.
Desmo Service Importance:
Skipping or delaying Desmodromic valve service can lead to significant engine damage and performance degradation due to improper valve lash.
Throttle Response:
Early models might exhibit slightly snatchy throttle response; ECU remapping or adjustments covered in the manual can mitigate this.
Electrical Connectors:
As with many European motorcycles of this era, ensuring electrical connectors are clean and well-seated can prevent intermittent faults.
