Polini Motori - new Racing and R&D Department


Recent news from Polini Motori, the legendary scooter parts and performance specialist has opened a completely remodelled and restyled new Racing and R&D Department at its headquarters just outside Bergamo.

The 2,000 sq m facility is "entirely dedicated to conceiving, designing and developing our core 'Special Parts' programmes, with the emphasis on working ergonomics - functionality and efficiency".




Polini's remodelled in-house R&D centre now provides some 2,000 sq m of ergonomically efficient space, designed with the same attention to detail and style that its entire headquarters facility is famous for.

Reimagined with attention right down to the smallest detail and tolerances, "the latest generation technology, advanced quality control equipment and optimised working procedures facilitate the processing of our special parts designs by our specialised and experienced staff, under the direction of our technical managers, Denis and Iuri Polini.

"The goal remains the same - to establish more and more the value of Polini as a leading brand in the production of spare parts and special parts for scooters and motorcycles, electric motors for e-bikes and paramotors for flight".


This ECM and valve spring upgrade kit for Euro 5 4-stroke Vespa and Liberty 50 models offers three map settings.


Recent new products include a Polini ECM and valve springs upgrade for Euro 5 Vespa and Liberty 50 4-strokes.

Developed and designed by the Polini racing department, the ECM upgrade allows choice of three tuning maps; the addition of Polini valve springs lets the restrictor reach all the way up to 10,000 rpm with improved speed and performance and a more dynamic response and smoother handling.


Polini's Vespa 125 Primavera ET3 street muffler has evolved to offer a racing version with increased 29 mm manifold.


The original Polini muffler has now evolved into a racing version, recommended for Vespa 125 Primavera ET3 tuned engines.

"It fits perfectly with the original frame, both in terms of space and aesthetics, with its shape and embossed Polini logo evoking the iconic street performance mufflers that have been a hallmark for a generation of Vespa riders".

Recent additions to the Polini 'Variator' programme include the 4-stroke, Euro 5 Peugeot Speedfight (seen here), the 125 cc Yamaha XMAX (2021), Euro 5 Piaggio Beverly and MP3 400 HPE, and the 2-stroke Euro 4 and 4-stroke Euro 5 Peugeot Kisbee 50.


The 29 mm increased diameter manifold has been redesigned with a conical inlet and increased diameter exhaust pipe to increase performance while keeping the noise low. Interchangeable with the original, it allows 3.10-10 larger tyres to be installed.

Of course, one of Polini's best known and most popular performance parts programmes are its 'Variators'. Among the recent additional applications is the Euro 5, 4-stroke Peugeot Speedfight and NECO 50, delivering "thrilling performance without compromising safety or reliability".

Polini Maxi Speed 3G race clutch for maxi scooters with Piaggio Euro 5, 4-stroke 125, 150, 250 and 300 cc engines.


The half-pulley has been designed with a different belt travel angle for improved performance and the inside of the roller's sliding surface has been subject to a polishing treatment to reduce power- robbing friction. Rollers are available in a 5.3 g pack, coated with a new nylon and aramid fibre material. The spring load has been increased by 15%, while the clutch springs' load has been increased by 20% - increasing the clutch engage by 600 rpm.

Additional recent new 'Variator' applications include the 125 cc Yamaha XMAX (2021), Euro 5 Piaggio Beverly and MP3 400 HPE, and the 2-stroke Euro 4 and 4-stroke Euro 5 Peugeot Kisbee 50.

This new Euro 5 Vespa 125 GTS and GTS SUPER, i.e. 4T 4V, muffler design - available with or without catalyst - is around 3 kg lighter than stock.


The new Polini Maxi Speed 3G race clutch for maxi scooters with Piaggio Euro 5, 4-stroke 125, 150, 250 and 300 cc engines has been conceived to better resist the stress of the maxi scooter transmission, especially at starting. It is designed with three centrifugal masses for perfect balance and greater uniformity of friction.

It is adjustable (without disassembly from the transmission) and "can be calibrated to obtain the best setting for both touring and race use in track competitions. The friction material has been specified for high grip and exceptional resistance to abrasion at high temperatures".

For Vespa models, this updated Polini cast iron big bore cylinder kit with 68.5 mm cast iron cylinder increases the displacement to 210 cc and delivers +12% greater performance (at the same rpm) than its prior version.


For the Euro 5 Vespa 125 GTS and GTS SUPER 4T 4V, Polini has a new muffler design - available with or without catalyst. Easy to assemble, it is very light, weighing around 3 kg less than the stock muffler for increased performance and optimised engine tuning, especially in sprint and pick-up terms.

Equipped with an aluminium end cap with a modern design and carbon-like texture, it has a gritty but pleasantly muffled sound, thanks to the use of sound-absorbing materials that keep the noise level within the regulatory limits.

Vespa Special/Primavera/ET3 clutch case - interchangeable with the stock design, it has a rackwork pusher that allows fluid sliding with low friction coefficient. Suitable for standard and upgraded spring load clutches on race spec engines.


The research and development staff of Polini Motori presented the cylinder kit for Vespa 200, increasingly modernising all its parts in order to improve performance and reliability.

Finally, and also for Vespa models, this Polini cast iron big bore cylinder kit with a 68.5 mm cast iron cylinder increases the displacement to 210 cc. Featuring a new duct and exhaust port design for increased engine efficiency, the completely redesigned piston has larger passages on the skirt to help feed the transfer lines.

A "must-have" for tuners, this increased internal volume filter box with mixer for Vespa PX125/250 and PE 200 models delivers increased performance and improved durability for original or upgraded SI carburettors.


The increased finning on the head allows for maximum heat dispersion and the dome is entirely machined and coupled with a copper gasket to improve performance and optimise cooling; the dowel pins with the cylinder allow for a constant squish area over the entire diameter of the cylinder.

Polini says that its R&D team has designed this cylinder kit for a 12% performance increase compared to its previous model, at the same rpm.

Founded in 1945, Polini sells to some 3,200 distributors and dealers in 64 countries worldwide.
