Description
Dual intake manifold Polini PHBL Vespa PK 50 / 125
The Polini dual intake manifold for Vespa is a metal intake system that draws air both through a direct intake on the engine casing and through a reed intake on the cylinder. This setup improves cylinder filling and delivers an estimated power increase of about 2–3%.

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!
