Engine Type 125:
Single-cylinder, four-stroke, air-cooled (likely based on Minarelli or Piaggio derived engine).
Engine Type 150:
Single-cylinder, four-stroke, air-cooled (likely a slightly larger displacement version of the 125cc engine).
Bore Stroke 125:
Specific values would be detailed in the manual, but typically around 52mm x 58.6mm for a 125cc air-cooled four-stroke.
Bore Stroke 150:
Specific values would be detailed in the manual, but typically around 57mm x 58.6mm for a 150cc air-cooled four-stroke.
Horsepower 125:
Approx. 10-12 HP (varies by specific tune and market).
Horsepower 150:
Approx. 12-14 HP (varies by specific tune and market).
Torque 125:
Specific values would be detailed in the manual, typically around 8-10 Nm.
Torque 150:
Specific values would be detailed in the manual, typically around 10-12 Nm.
Carburetor Type:
Likely a Mikuni or Keihin CV-type carburetor (specific model and size provided in manual, e.g., VM26 or similar).
Fuel Type:
Unleaded gasoline (minimum 91 RON).
Engine Oil Change:
Every 3,000 - 5,000 km or annually (specific interval in manual).
