Electrical Connections:
Corrosion or loose connections in wiring harness, particularly around the regulator/rectifier and stator. Vibration can exacerbate issues.
Carburetor Issues:
Carburetor can become gummed up if the bike sits for extended periods, leading to starting and running problems. Jetting might need adjustment for altitude or modifications.
Suspension Seals:
Fork seals can wear over time, leading to oil leaks. Rear shock absorber may lose damping over high mileage.
Clutch Slippage:
Clutch plates can wear, leading to slippage, especially if the bike is used aggressively or ridden with a passenger frequently.
Chain And Sprockets:
Wear on chain and sprockets is normal, requiring regular adjustment and eventual replacement. Proper lubrication is key.
Manufacturer:
Aprilia is an Italian manufacturer with a strong racing heritage, known for performance motorcycles.
Development:
The Pegaso 650 was developed as Aprilia's entry into the popular mid-weight adventure/dual-sport segment.
Engine Source:
The Rotax 654cc engine (often based on Rotax design, manufactured by Aprilia or Rotax) was a key component, known for its reliability and torque.
Variants:
The Pegaso 650 saw several iterations and updates during its production run, including the 'i.e.' (fuel injected) versions later in its life.
