VESPA 300 GTS KIT - PIAGGIO BEVERLY EURO 3 and 4: AN EXPLOSION OF POWER
Borrowing the technology used in Formula 1 engines, Polini Motori has designed a thermal unit that marks a milestone in the tuning of Piaggio 300 engines.
Thanks to the special steel barrel with Nicasil coating and the HTR (High Turbulence Ring), it has been possible to increase the diameter up to 77 mm, taking the displacement from the original 278 cm3 to an impressive 294 cm3: an explosion of incredible power for your scooter's engine.
The thermal unit can be mounted without any modification to the crankcase and the original cylinder heads. A unique feature in the scooter sector is the HTR ring, which not only improves the crushing effect, but also allows a large surface area of the head gasket, thus guaranteeing the high reliability of this component.
< p>The piston has a specially elongated shell to resist the considerable lateral thrusts generated by the connecting rod; The combustion chamber carved into the upper part of the piston is shaped to have an optimal compression ratio with wide crushing bands that adapt to the original cylinder head.The control unit has two specific curves for the different steps tuning: the first is indicated for assembly with Polini Hi Speed variator, kit and original silencer; The second is indicated for assembly with Polini Hi Speed variator, kit and Polini silencer.
The performance with the new kit is palpable already from low revolutions and the engine performs at any speed.
< p>The kit is supplied complete with Plug & Play equipped with the relative wiring to connect to the original system without modifications.Code 140.0224
