Polini has created a new head for the Vespa 125 Primavera ET3 characterized by the centrally positioned spark plug hole. This optional was produced after the numerous requests of the most demanding pilots to maximize the performance of Polini kits with aluminum cylinder. The specific squish increases the compression ratio, optimizes combustion and improves overall performance.
TECHNICAL FEATURES
The head is cast in light alloy in one piece to increase heat dissipation.
Additional flaps have also been created under the plane of the head, always to better dissipate the heat.
Attention: for the assembly of the evolution head with the central hole it is necessary to modify the head cover.
