Dellorto Performance 22mm Auto-Choke Carburetor Kit for Aprilia / Piaggio 50cc 2T Models


Finally! A performance carb kit with an Auto-Choke! Virtually a direct upgrade from the standard PHVA 17.5 it has been specifically designed to fit the Piaggio Hiper2 engine found in almost all Aprilia and Piaggio 50cc 2T scooters (such as Aprilia SR50R, Sportcity 50 2T, SRMT 50 & Piaggio Zip 50 2T, Typhoon 50)

We’ve put this kit together specially, for super easy install. Included in this kit is the Dellorto Genuine Auto-Choke, as well as the correct larger intake manifold to suit this carb, as its a tight squeeze getting it into the factory manifold. This is the best value carb kit we have!

Depending on your airbox, some modification may be required to get the carb inlet to fit inside the airbox outlet as the PHVB inlet is larger than the stock carb. We do also have a Malossi Pod filter available to direct fit this carb, just click the ‘PHVB Tuning Items’ link below to see.

Dellorto Performance 22mm Auto-Choke Carburetor Kit for Aprilia / Piaggio 50cc 2T Models

Generally, a performance carburetor is bigger than a standard factory carb, which allows the engine to suck more fuel and air – which in turn gives you more power.

The Malossi PHVB carburetor series is designed and manufactured by Dellorto in italy. Malossi have put years of research and development into these carbs, and have chosen the exact specifications of the Dellorto PHBB because of its high quality, performance value and ability to be precision tuned.

The PHVB (unlike the PHBG) is an Auto-Choke carb! It uses the standard auto-choke from the standard PHVA 17.5 fitted to all Aprilia/Piaggio 50cc Hiper2 motors.

*Performance scooter parts do not come with a warranty* Similar too M1611029.

An essential part of your scooter engine, don’t leave it out of your tuning package.
