⚙️ Engine Specifications

Engine Type:

Single-cylinder, four-stroke gasoline engine

Engine Displacement:

247 cc (for the 250) or 298 cc (for the 300).

If '750' implies a modified or specific variant, precise displacement would vary, but historically the 750cc designation isn't standard for Isetta.

Varies by specific model, e.g., 68 mm x 68 mm for 250cc

Horsepower:

Approximately 9.5 to 13 hp (for 250/300cc models). Higher figures for 600cc models.

Torque:

Low torque, characteristic of small displacement engines of the era.

Fuel Type:

Unleaded gasoline
