Engine Displacement:
Approximately 650cc.
Bore X Stroke:
Specifications would be detailed within the manual (e.g., typically around 100 mm x 83 mm for Rotax 654).
Compression Ratio:
Specifications would be detailed within the manual (e.g., typically around 10:1).
Horsepower Range:
Approximately 45-50 HP, depending on specific model variant and market restrictions.
Torque Range:
Approximately 55-60 Nm, depending on specific model variant.
Fuel Delivery:
Either Carburetor (e.g., Mikuni BST40) or Electronic Fuel Injection (EFI) depending on the specific 2005+ variant.
Fuel Type:
Unleaded gasoline.
Ignition Type:
Electronic ignition (CDI or similar).
Cooling Method:
Liquid-cooled.
Oil Type:
High-quality motorcycle specific 4-stroke engine oil, e.g., SAE 10W-40 API SG or higher, JASO MA certified.
Oil Capacity:
Approximately 2.0-2.5 liters with filter change (exact capacity to be verified in manual).
Length:
Approx. 2170 mm (Varies by specific model variant).
Width:
Approx. 840 mm (Varies by specific model variant).
Height:
Approx. 1440 mm (Varies by specific model variant, including windscreen).
Dry Weight:
Approx. 168 kg (Varies by specific model variant).
Fuel Capacity:
Approximately 14 liters (including a small reserve).
Oil Change Interval:
Typically every 5,000 - 7,500 km or 6-12 months, whichever comes first (refer to manual for precise intervals).
Air Filter Interval:
Inspection every 5,000 km, cleaning/replacement as needed.
Spark Plug Interval:

Engine Specific Considerations:
Rotax engines are generally robust but require diligent maintenance. Oil level checks are critical.
Electrical Common Faults:
Can include stator or rectifier failure leading to charging issues, or corroded electrical connectors.
Manufacturer:
Aprilia is an Italian manufacturer known for its performance-oriented motorcycles, particularly in the sport and off-road segments.
Pegaso Lineage:
The Pegaso nameplate has a long history with Aprilia, evolving from earlier dual-sport models. The 650cc engine, often sourced from Rotax, became a staple for its versatility.
Production Period:
The Pegaso 650 was produced for many years, with the 2005 onwards models representing a significant update and continuation of this versatile platform.
