POLINI electronic control unit ECU 1123583

KIT VESPA 300 GTS - PIAGGIO BEVERLY EURO 3 and 4: UNA EXPLOSIÓN DE POTENCIA
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 Nicasil-coated special steel barrel and the "HTR" (High Turbulence Ring), it has been possible to increase the diameter up to 77mm, taking the displacement from the original 278cm3 to an impressive 294cm3: an explosion of incredible power for your scooter's engine.
The thermal unit can be mounted without any modification on the original crankcase and 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 head gasket surface area, thus ensuring the high reliability of this component.
The piston has a specially elongated cap to resist the considerable lateral thrusts generated by the connecting rod; The combustion chamber carved into the top of the piston is shaped to have an optimal compression ratio with wide crush bands that match the original cylinder head.
The control unit has two specific curves for the different tuning steps: 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 benefits with the new kit are already palpable from low revs and the engine performs at any speed.
The kit is supplied complete with a Plug & Play control unit equipped with the relative wiring to connect to the original system without modifications.
