When assessing the price of a GN125, you must look beyond the sticker price and evaluate the engine configuration (typically a 124cc single-cylinder, 4-stroke, air-cooled engine). Ensure the unit features a Euro 4 or Euro 5 compliant fuel injection system (EFI) if required by your local regulations, as carbureted versions are cheaper but restricted in many markets. Additionally, verify the braking system (front disc/rear drum is standard) and the fuel tank capacity (usually 10L-12L), as these components directly impact the manufacturing cost and retail value.
