Vespa ET4: the classic four-stroke scooter, what to know when buying
Vespa ET4 — the four-stroke scooter produced from 1996–2005 with a 125 or 150 cm³ engine. We look at the versions, tech, and what to check when buying used.
ET4 in brief
The Vespa ET4 was one of the first modern four-stroke Vespa scooters. It stands out with its classic Vespa styling, comfortable seat, and smooth handling, making it ideal for city driving and shorter trips.
The four-stroke engine offered better fuel efficiency and smoother operation than its two-stroke predecessors, making the ET4 a popular choice for urban commuting.
Versions
The ET4 debuted in 1996 with a 125 cm³ four-stroke engine, later joined by a 150 cm³ version. There are also versions with a 50 cm³ engine, so when buying, check the specific scooter's displacement and category.
Throughout its production run, the styling, trim, and colors changed, but the core technology remained largely the same.
Engine and transmission
The engine is a single-cylinder four-stroke, usually 125 or 150 cm³ displacement, air-cooled. Power is ample for city driving. The transmission is an automatic with a variator.
This type of engine is known for its simple maintenance and low fuel consumption.
What to check when buying a used ET4
Due to its age, check for corrosion on the bodywork, especially in the lower sections. Inspect the brakes, suspension, and tyres.
Request the service history: oil changes, variator and clutch condition, valve clearances. Check if the engine starts easily and runs smoothly.
Check the electrical system, lighting and documents, especially if the scooter is imported from abroad.
