140.0234

Polini Evolution 3 cylinder kit for Vespa 125 Primavera ET3. Polini code: 140.0234

The strong point of the new kit is the possibility of mounting it on original Vespa crankcases avoiding boring the crankcases.

A particular feature of this cylinder is the assembly designed to work both in the original position and in the classic twisted version often used in track racing.

This position facilitates the development and assembly of the muffler.

The engine gains more power at each rpm.

The Polini Evolution 3 kit for Vespa with rotary valve intake can be mounted on all types of Vespa 125 with crankshaft of the same size as the original.

TECHNICAL FEATURES of the Polini Evolution 3 kit for Vespa

The cylinder is cast in aluminium, with a ø 58mm bore. for a displacement of 135cc.

The barrel with Nickel-Silicon coating improves the sliding of the piston, resistance to wear and abrasion.

Very "racing" distribution diagram. Six racking ports.

The forged piston is equipped with two chromed S10 cast iron rings. The head is cast in a single piece and to increase heat dissipation, additional fins have also been created under the surface of the head. The compression ratio has been designed to obtain maximum performance.
