Originally fitted to the Vespa T-5 (a hot rod 125cc from the 1990's), but will also fit most any classic style large frame Vespa from 1960-2005 (with injector style air box NOT included) and all years of the Stella (does not fit GS or SS). This kit includes a 24/24G injector T5 type carburetor (an original Dellorto by Spaco), T5 air filter, box lid and hardware to run this on most large frame Vespas. The Carburetor is the heart of your motor, give it new LIFE, give it new POWER, give it a new carburetor. Your scooter will thank you with quicker starting, improved gas mileage, enhanced performance, and better all around reliability. A great deal at any price.
