"for competition only! Not allowed in the German StVZO area! An unconventional power pack, this cylinder sharpens your sporty image of the T5. In contrast to the original T5 cylinder, this goodie tuning is cut out for performance in the low range and can take your breath away with awesome starts. POLINI produced this beauty in their traditional way with a clean cast iron cylinder finished with 6 transfers. The original PIAGGIO 125ccm cylinder, in comparison, is made of aluminum. Again, the POLINI is fun to drive, and used in conjunction with the original 24Si carburettor, it is trouble-free in city traffic. For trips in the countryside or on the motorway a longer transmission, sports exhaust and larger 28mm carburetor is required. A modified cylinder head is important for all versions. Here we recommend Highlight CNC from MMW. To increase the dispersion of the necessary heat, it is recommended that you spray paint your black cylinder. Same bigger is the PX 208 POLINI or 210 MALOSSI, there are other simple and effective methods to reduce the lighter weight using the bi-conical GRAND SPORT plug. Call it "light tuning" if you like, your original crankcase will be grateful. Results: The price / performance winner for Vespa T5 models. Like all POLINI cylinders, abundant torque in the low range and performance to get go. An improvement over the original T5 cylinder.
