Description
Polini is one of the big names in 50cc scooter tuning, and is also one of the leading manufacturers of tuning parts for Vespa, modern and vintage. Cylinders, intake manifolds, exhausts, air filters, carburetors, crankshafts and more - everything you need to boost the performance of your Classic Vespa.
Polini Intake Manifold (disc valve) d=28mm 2-hole Vespa 125cc Primavera, solid mount aluminium intake manifold for Vespa 125cc Primavera. The intake system consists of a solid mount aluminium intake pipe, a rubber adapter and all small parts needed for assembly. If you are looking for a boost to your engine and installing a reed control intake is too much of a hassle as it involves some major modifications, this Polini manifold, combined with a bigger carburetor, provides great intake performance.
We recommend getting a manifold with appropriate diameters (carburetor + air filter). Choosing the wrong intake manifold can lead to more air turbulence and worse air intake, and the engine will not be able to breathe efficiently. Choosing the right intake can get you noticeably more power.
- intake manifold, aluminium, diameter = 28mm
- carburetor connection = 36mm
- 2-hole connection
- for PHBH / PWK 28 - 30mm carburetors
Intake manifold for scooters, motorcycles, and mopeds
The intake manifold is an essential part of the intake system, it directs the air-fuel mixture to the cylinder. Here are the main types of intake manifolds:
Intake manifold with rubber flange
Intake manifolds with flexible intake rubber are the most common type. Flexible materials such as rubber or silicone absors the vibrations of the engine. This flexibility reduces the risk of cracks or leaks. In addition, the flexible mounting makes it easy to adapt the intake manifold to different engine setups.
Intake manifold with metal flange
These rigid-mount intake manifolds are more commonly used on vintage scooters, classic motorcycles or old mopeds. The intake flange is usually made of metal, which provides greater strength and resistance to deformation. Rigidmetal flange assembly also ensures more precise alignment between intake manifold and carburetor.
Swivel intake manifold
Rotatable intake manifolds are commonly used on 50cc motorcycles. They offer greater flexibility in installation, allowing to align the carburetor to meet individual needs.
Note: The diameter of the intake manifold must fit the intake manifold connection width of the carburetor!
