The Vespa T5 it is a 125cc, single cylinder, 2 stroke scooter which was manufactured by Piaggio. The Vespa T5 was a true sporting scooter featuring an improved 5 port aluminum cylinder design allowing for greatly improved power and cooling, and higher revs, compared to its largeframe cousin, the PX. The squarish (55 x 52 mm) and lightweight piston design was aimed for high revs, as was the aluminum cylinder with Nikasil plating, the lightened flywheel, and the shorter 24mm carburetor (Dell'orto 24/24 G), all introduced with the model.
