Polini expands carburettor and fuel systems range


Following the positive market response to its high-quality carburettors, Italian scooter performance specialist Polini Motori has built on that foundation with a range of fuel system kits.

With CP Polini carburettors internationally recognised for their performance and reliability, Polini's complete line of fuel systems has been specifically designed for scooters, Vespa, and 2-stroke motorcycles.


They have been developed to be application specific, and tuned to ensure maximum performance and efficiency. Each kit can include a manifold that has been designed to optimise air and fuel flow, a high efficiency air filter for clean and powerful combustion and the carburettor - calibrated for the specific characteristics of the engine and the reed valve for improved throttle response.

Available in a wide range of diameters (15/17.5/19/21/23/24 mm), the CP Polini carburettor is made entirely of aluminum, featuring compact dimensions and 40% less weight compared to a traditional carb.

The concentric design and geometry of the very short intake duct stands is exclusively optimised to enhance air flow during the gas transit phase, with fuel overflow into the atomiser designed to ensure proper flow dynamics at any throttle position.

The fuel inlet hole and the larger needle allow for consistent fuel delivery, even under the most extreme conditions. The plastic float level and the needle seal are carefully checked during production to ensure consistent efficiency standards over extended use - significantly simplifying the carburettor's tuning setup.


The refined tuning scheme means the air-fuel flows, main jet, and idle jet are designed to deliver maximum performance with reduced fuel consumption. The compact size of the new carburettor required careful optimisation of internal space and maximum efficiency of all components - to stringent and precise millimetre-level tolerances.

Flanges are available in various diameters to ensure easy and precise installation on the most common engines and compatibility with different genuine and racing air filter boxes.
