Vespa SEI GIORNI Replica Project

Created by Jenni at 12:01 on January 31, 2019

“Heritage” is not a commodity, you either have it or you do not. Vespa scooters have a glorious history, mostly due to a few particularly attractive models. The Vespa Sei Giorni factory specials represent both the myth and legend of sporting scooters. The Sei Giorni (six days) trial rally took place in the early fifties and PIAGGIO were victorious with their 'PIAGGIO Squadra Corse' racing team, defeating all potential rivals. These 'Ufficiale Piaggio' were all factory race machines, produced a mighty 7 PS from their 125cc motors and are now known as the Vespa Sei Giorni models. 

They are considered as the ultimate goal of any serious Vespa collector or museum, with only ten to fifteen examples still in existence worldwide. If such a Vespa becomes available then only at prices around Є 150,000! 

Our sales assistant Olli decided to realise his personal scooter dream and build himself a road-going replica of the legendary Sei Giorni Vespa models.

“It all began with the purchase of an original Sei Giorni fuel tank from 1953. I bought it from my friend and mentor Robin Davy, who no longer needed it. I was always fascinated by the Sei Giorni Vespa models but ownership is difficult, mostly due to their price and rarity. This inspired me to build a replica model, identical to the original factory Vespa models. 

The project kicked off early in 2009. After a couple of months, I discovered a Vespa Messerschmitt T2, providing an initial basis. It proved ideal due to its external control cables, a similarly slender frame spar along with the typically bulbous sidepanels. 

Then the panel beating stage was reached, legshield remodelling, sidepanel modification and attachment, along with numerous other details had to be taken care of. The modified V30 steering column, with its trailing-link suspension, required a lot of attention to detail. The adaptation and narrowing of the steering assembly, complete with a quick-action throttle, was especially time-consuming. 

My main incentive in this project was to include as many original components as possible and managed to organise an original single-seat, footboard strips, horn, rear light, headlight and various original fixings for my replica Vespa.

The Sei Giorni models profile is dominated by the fuel tank and the special wheels, which were especially difficult to source. They have the model-exclusive dimensions of a 10” brake drum combined with an 8” wheel rim! 

As I intended to use this scooter as an everyday runabout and commuter the engine had to look as original as possible but still provide decent road performance. An ideal solution was provided in the form of a GS 150 engine fitted with a 172cc Quattrini aluminium cylinder combined with an external Polini CP carburettor. The four-speed gearbox and the motors 20PS ensure a sporty riding experience!

The paintwork required a few artistic tricks for additional authenticity. My Sei Giorni is inspired by an almost seventy year old Vespa, it posed a real challenge to provide the aesthetic icing on the cake. Emery paper, numerous slightly different shaded layers of paint and acids came to use and the result was truly astonishing! Dream realised and now the result of my efforts will be parked in front of our SIP store this summer, as my daily ride!”
