Motovespa Luftfiltereinsatz bgm PRO

Air filter insert bgm for Motovespa air filter

The identical air filter inserts are fitted to many Motovespa Largeframe models. Often this important component for the protection of the engine is missing or is no longer in a usable condition. For this reason, we have produced a high-quality air filter insert for the Spanish licensed versions of the Vespa Largeframe models.

Air filter fleece bgm PRO for Motovespa Largeframe

High quality filter fleece from Marchald (Italy), manufactured for bgm PRO. Suitable for the direct-intake engines (carburettor sits directly on the cylinder) of the Largeframe Motovespa engines.

  • 1:1 replacement for the original wire mesh.
  • Significantly better and finer filtration with higher air flow at the same time.
  • Therefore also ideal for already performance-enhanced engines.
  • Washable.

Installation instructions for the Motovespa air filter element

Replacing the air filter element is very easy. After removing the right side cover, the air filter box is immediately visible.

Motovespa Luftfilterkasten Vespa

Open and remove the air filter box

The cover is fixed with two M5 screws. These can be loosened with a size 5 to 6 flathead screwdriver.

The air filter of the Motovespa

After removing the two screws, the cover can simply be lifted off. Here, in our example, the original air filter insert of the Motovespa is no longer present!

Attaching the air filter element

The air filter insert has no installation orientation and can simply be pushed onto the filter housing from above.

Closing the air filter box

The remaining protrusion of the air filter insert seals towards the air filter box cover when mounted. Refit the cover of the air filter box with the two screws, refit the side cover and the change is complete.

Air filter cleaner and oil

To achieve an even higher filter performance, the air filter insert can be used with air filter oil. However, this is not absolutely necessary due to the high-quality filter material of the bgm PRO filter.

New extra flat bgm PRO air filter for CP caburettors

bgm PRO air filter for Polini CP carburettors

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

Extra flat air filter specially designed for Polini CP carburettors. Available in two sizes:

With a thickness of only 30mm this filter is perfect for the Vespa Wideframe or tuned-up Lambretta.
The 55mm version is also a good option for the Vespa Smallframe.
The BGM filter has been specially developed for CP carburettors. The air filter rubber perfectly follows the shape of the carburettor and this prevents any risk of slippage.

The bell mouth perfectly fits the carburettor and has therefore a streamlined form. Thanks to the compact form and the high permeability of the filter material, this filter is the best option if you want to have a perfect air intake without having a power loss.

Features of Marchald Power Double Layer air filter

  • easy and quick to assemble
  • high filtration performance and optimised air flow thanks to the double layer high tech foam
  • superb airtight rubber, no risk of air leak
  • water resistant – even after complete wetting the filter has not to be replaced
  • washable
  • thanks to the very flat design this filter can be fit in the smallest space
  • integrated bell mouth for best inflow of the carburettor

The length refers to the additional length (millimetres) of the carburettor/filter group after mounting the filter.

Polini CP carburettors

The Polini CP carburettors, characterised by their compact design, are very popular and widely used.

 

The CP carburettor can be used to replace the genuine carburettor of the Smallframe models or to get more power on Vespa and Lambretta engines: indeed, it is characterised by a compact design and therefore offers much better setup options than SHB carburettors.

bgm PRO / Marchald cooperation

We decided to cooperate with the Italian company Marchald, specialised in air filters, and to develop together what we consider the perfect air filter for the CP carburettors.

 

High quality and broad experience in air filter development

The high-quality rubber, which Marchald has used for years, can resist to steady mechanical stress and chemical exposure.

In order to ensure a perfect adherence and to prevent any risk of slippage, the rubber perfectly follows the shape of the carburettor.
Thanks to the two grooves in the rubber and the clamp (also included in the item) the air filter is stably fixed in its place.

Together with its bell mouth the rubber perfectly adapts to the special shape of the CP carburettor, a shape which increases the performance of the carburettor.

 

Air filter available in two sizes

Depending on place available to mount the filter, we have designed this air filter in two versions.

The length reported in the item description refers to the length of the filter once it has been mounted on the carburettor.

The BGM air filters fit all Polini CP carburettors from Ø17,5 to Ø24mm and are available in two sizes: 30mm and 55mm.

 

 

For Vespa Smallframe: 55mm air filter

The 55mm version is a good option for the Smallframe models. Even though the shock absorber is fully deflected, there’s still much space between the air filter and the chassis.

For Vespa Wideframe, Smallframe and Lambretta:

The 30mm version is particularly ideal for the Vespas Wideframe since they can be mounted even in small spaces.

With a length of only 30mm, this filter is short enough to prevent any crash or pressure against the carburettor flap.

 

 

If you use this filter on a Vespa Smallframe you’ll have much more space around the carburettor.
