Vespa Et4 150
The Vespa Et4 150 has a top speed of 105 km/h, produces 11 hp and weighs 115 kg. Motoryk rates it 7.5/10.
La Vespa ET4 150 a été introduite par Piaggio en 1996 dans le cadre de la série ET moderne, marquant la transition de Vespa vers un scooter à moteur quatre temps tout en conservant son style emblématique. Elle s'est distinguée par le fait qu'elle a été l'une des premières Vespas à adopter un moteur monocylindre quatre temps à injection de carburant, le rendant plus propre et plus économe en carburant que ses prédécesseurs à deux temps. L'ET4 150 a été vendue jusque vers 2005 et a contribué à revitaliser la marque Vespa auprès des navetteurs urbains du monde entier.

Ce que les acheteurs doivent savoir
Reliable Rotax Engine
The ET4 150 uses a Rotax-sourced 4-stroke engine, a significant upgrade over older 2-stroke Vespas, offering smoother power and lower maintenance costs. With proper oil changes, these engines routinely exceed 30,000 miles.
Watch the Carb & Fuel System
Ethanol-blended fuels can degrade the carburetor and fuel lines on older ET4s, causing hard starting and rough idling. Always inspect these components and budget for a carb clean or rebuild if buying a neglected example.
Strong Resale Value
The ET4 150 holds its value well due to the iconic Vespa brand and its transition-era status as a practical, modern classic. Clean examples in good condition typically sell for $1,500–$3,000 depending on mileage and cosmetics.

Lancement original de l'ET4 150 avec moteur Piaggio LEADER 4 temps de 150 cm3, fourche avant unilatérale et style moderne.
"Le charme italien enfin associé à un moteur adulte."
Après des années de Vespa à deux temps qui exigeaient un ajustement constant, l'ET4 150 semblait être une révélation : des rebondissements, aucun rituel d'étranglement, aucune culpabilité liée au prémélange. Le moteur LEADER tourne doucement au ralenti et fonctionne confortablement à 80 km/h toute la journée, sans le bourdonnement intense que l'on ressentait sur les anciens véhicules à deux vitesses, bien que 95 km/h soit un chiffre théorique sur tout sauf sur un asphalte plat. Cette fourche avant unilatérale a l'air incroyablement cool sur les photos, mais elle transmet les imperfections de la route avec un aspect légèrement boisé et vague qui vous déstabilisera au milieu des virages sur un asphalte urbain irrégulier. C'est un choix de style que Piaggio a privilégié par rapport à la sensation. L'aspect pratique est vraiment une bonne chose : le rangement sous le siège permet d'accueillir un casque intégral, la carrosserie en acier résiste aux chocs sans se briser et la consommation de carburant d'environ 35 km/L réduit les coûts de fonctionnement, mais les premiers modèles à carburateur sont sujets aux inondations s'ils sont laissés en place plus d'une semaine.

Évaluation d'un acheteur d'occasion
"Rewarding urban scooter if you buy one carefully maintained."
$1,500-$3,500 usedThe ET4 150 is genuinely charming in a way that makes you forgive its quirks — and trust me, there are quirks. Piaggio's rotax-derived engine pulls smoothly to about 60mph, which is honestly all you need for urban commuting. The bodywork is proper steel, not plastic, so it holds up well used but also means rust is your enemy on neglected examples. Check every panel seam and under the floorboard religiously before handing over cash. Electricals are the real headache on high-mileage units. Stators die, carburetors gum up from sitting, and finding a mechanic who actually knows Italian scooters outside major cities is harder than it should be. Budget $200-400 for a proper service immediately after purchase regardless of what the seller claims. The suspension is surprisingly composed for a scooter, and that classic Vespa silhouette genuinely never gets old — people will stop you at traffic lights wanting to chat. Buy one with documented service history and under 8,000 miles if you can find it. Walk away from anything that's been sitting more than a year without recent fuel system work.
