Quality and tradition from Cabiate, Italy.

DELL'ORTO – The History

The first carburettor to roll off the production line at the newly established factory in Cabiate, north of Milan, in 1933 bore the rather unpoetic name ‘SC 26’, but it soon became known commercially and colloquially as the ‘Rex’. Its customers included Moto Guzzi, Benelli and, even back then, Piaggio. All stages of production – including die-casting, machining and assembly – were carried out in-house by DELLORTO.
In 1940, the company ventured into motor racing and began producing high-performance carburettors.
Twenty years later, DELL’ORTO was supplying manufacturers such as Alfa Romeo, Ford, Lotus, Lancia and others with a new generation of carburettors. DELLORTO carburettors were indispensable in four-wheeled vehicles. In 1990, the Italians began manufacturing a new component: the Throttle Flap was developed in accordance with national and international environmental standards.
In 2000, the third generation of the Dell’Orto family joined the company, but Giuseppe has been the driving force behind the business for 50 years – its president and the heart of the company – supporting the new generation: Andrea is the Executive Vice President, Sales & Marketing Manager and Chairman of Dell’Orto India Pvt. Ltd. Luca has been Managing Director at DELL’ORTO since 2014, and the third member of the trio is Davide Dell’Orto, who serves as a board member and CTO.
In 2006, difficult times began for the Vespa’s two-stroke engines when the Euro 3 standard came into force. DELL’ORTO developed the Electronic Carburetion System (ECS), which enabled compliance with the new, stringent limits on pollutant emissions. Production in India began in the same year. Since 2008, the Italian company has been involved in the production of the ‘Tato Nano’, also known as the ‘People Car’, which is used in developing countries.

Since 2011, DELL’ORTO has been the exclusive supplier of Control Units to the ‘International Motorcycle Federation’ without interruption. In the Moto3 racing series, the unit handles the entire management of the racing engine, including software calibration and data acquisition. In 2019, this involvement was extended to the MotoE class.
To mark its 80th anniversary in 2013, DELL'ORTO strengthened its partnership with the Bosch Group and opened up its distribution network to them. Five years later, the strategic joint venture with Varroc marked a milestone for the company. Together, they are developing fuel injection systems for the Indian and global markets. DELL'ORTO sees itself as a global systems integrator for two- and three-wheeled vehicles. Since 2020, DELL’ORTO has also been focusing on the future of mobility and has formed a joint venture with Energica Motor Company to produce power units for small and medium-sized electric vehicles.
Today, in addition to its headquarters in Italy, DELL’ORTO has branches in India and China.
DELL'ORTO - The different series
"I remember the first time I met two guys from Germany who were passionate about scooters at the fair in Milan. Since then, DELL'ORTO has established a long-lasting cooperation with the company, which became one of the market leaders. SIP Scootershop has great expertise in the products and attention to the customer."
–Stefano Prandini, Aftermarket Manager, DELL'ORTO
For many years, DELL'ORTO carburettors have stood for more power when fitted to a Classic or Modern Vespa. They are often better tuned than the products of other manufacturers and are often factory-fitted on Piaggio, among others.
Classics, such as the SI 24.24, are often modified by tuners like the Denis Racing Team (DRT) or SIP Scootershop to build touring machines.
The PHB series of "drum carburettors", on the other hand, is the first choice for mid-range tuning and offers the greatest possible performance for relatively low cost.
For smallframe scooters, the SHB series carburettors are perfect. Whether 75 or 130 cc - with this carburettor, every engine is given a boost. Discreet and effective.
The flat slide carburettors from the VHSB series are among the largest and most powerful DELL'ORTO carburettors. They represent the top among the products for two-strokes. They are not only suitable for use on potent largeframe engines, but also for high-end smallframe setups.
Of course, there are many other models, but whichever one you choose - with a DELLORTO carburettor, every owner of a Classic or Modern Vespa gets outstanding quality.
