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.
