Description


POLINI KIT FOR VESPA 300 GTS AND PIAGGIO BEVERLY EURO 3 AND 4: POWER EXPLOSION

With the help of the technology used for the Formula 1 engines, Polini Motori has designed a new cylinder kit that wants to be a point of reference for Piaggio 300 engines tuning.

Thanks to the special barrel made of steel with Nicasil coating and to the “HTR” ring (High Turbulence Ring) it has been possible to increase the bore to 77mm, bringing the displacement from 278 cm3 to 294 cm3: an incredible explosion of power for your scooter engine.

The cylinder kit can be installed without any modification to the crankcase and to the original head.

Exclusive detail in the scooter market is the “HTR” ring that above improving the squish effect, it allows a larger supporting surface of the head gasket, granting great reliability of this part.

The piston has a wider skirt to resist to the side shifting generated by the coil; the combustion chamber, machined from the piston top, has been designed to have the best compression ratio with wide squish lines that match to the original head.


  • Bore: Ø77,0mm

  • Stroke: 63mm

  • Displacement: 293ccm

  • Kit includes: Complete cylinderkit with piston, rings, pin, clips and gaskets, CDI with wire group

  • To be used with original cylinderhead (Euro 3 and Euro4 (also HPE))

The CDI has two curves specific for the different tuning steps: the first is proper to be installed with Polini Hi-Speed, cylinder kit and original muffler; the second one with Polini Hi-Speed, cylinder kit and Polini muffler.

With the new kit the performance is tangible just from the first rpm and the engine is powerful at all the rpm.

The cylinder kit comes with plug and play CDI and the wirings to be connected to the original system without any modification.
