BGM PRO Double Layer Filter made by Marchald for Polini CP carburettors

Extra short air filter especially for the popular CP carburetor range from Polini. Available in 2 compact sizes:

With a depth of just 30mm, perfect for Vespa Wideframe or lamella tree structuresn suitable.
The 55mm version is also a very nice option for Vespa smallframe.
Form specially made for BGM especially for the CP carburettor. The connecting rubber takes up the contour of the carburettor and is therefore absolutely safe against slipping.

The indicated intake funnel adapts perfectly to the carburetor. Hence very streamlined design. Together with the effective but very permeable filter material, it is probably the best solution for clean intake air without loss of performance.

Advantages of the Marchald Power Double Layer air filter

  • Quick and easy to assemble
  • High filter performance and optimized air throughput thanks to high-quality double-layer high-tech foam
  • Elaborate sealing edge, absolutely airtight closure of the adapter, therefore no additional air
  • Moisture-resistant - the filter does not need to be replaced even if it is completely soaked
  • washable
  • Thanks to the extremely flat design, it can also be used very well in places with little space
  • Integrated intake funnel for the best flow to the carburetor

The specified length indicates by how many millimeters the carburetor / filter assembly is effectively extended.

The Polini CP carburettors

The compact CP carburetor from Polini are very popular.


Whether as a replacement for the original carburetor one of the Smallframe-Models or to look for more power on the Vespa and Lambretta engines: The CP carburetor impresses with the compact design and significantly better setting options than the comparable SHB carburettors.

bgm PRO / Marchald cooperation

We sat down with Marchald, the professional in the field of air filter construction in Italy, and together we developed a perfect air filter for the CP carburettor according to our ideas:


Highest quality and great experience in air filter construction

The connecting rubber is made of the well-known rubber quality that Marchald has been using for years and is permanently resistant to chemical and mechanical loads.
So that the filter stays safely in its intended place, we have taken up the outer contour of the carburetor.
The air filter sits immovably in its place thanks to the two grooves incorporated in the connecting rubber and the clamp supplied.

The connecting rubber takes up the special and performance-increasing design of the CP carburettor with an adapted funnel.


Two air filter sizes available

There are two different versions so that the air filter can be used effectively in all areas.
Our length specification describes the dimension that is in front of the carburettor after the filter has been installed. So how much longer the entire carburetor / air filter assembly around the CP air filter will be.

The air filters generally fit all Polini CP carburettors from Ø17,5 to Ø24mm  and are available in two versions. Once in 30mm length and once in 50mm length.



For Vespa Smallframe: 50mm air filter

The 50mm variant fits very well into the Smallframeuse s. Even when the rear shock absorber is fully compressed, there is still enough space to the frame for the bgm air filter.

For Vespa Wideframe, Smallframe and Lambretta:

The 30mm variant works well on the Lambretta and especially in the cramped conditions of the Vespa Wideframeuse s.

With only 30mm is the filter short enough so as not to hit the carburetor flap and push it open.



In the Vespa SmallframeThere is a lot of space in the carburetor compartment with the 30mm long filter.
