This SIP Adapter Plate enables the vast range of potential exhausts available for smallframe Vespa models to be successfully combined with the POLINI-EVO II cylinder.
The adapter plate is attached to the cylinder using two countersunk M8 Allen bolts.
The pair of M7 studs，that are already welded firmly to the plate，enable the attachment of an exhaust.
The plate is made of galvanized steel to protect it against corrosion，even being able to survive harsh Winters and the inevitable road salt and grit etc.！ The POLINI-EVO II cylinder itself is equipped with exhaust studs which unusually protrude at a diagonal angle from the sides of the outlet port，making it almost impossible to fit any other exhaust apart from the dedicated POLINI-EVO II exhaust system！ This adapter is the ideal solution，enabling experimentation with other exhaust types in the quest for an ideal power delivery for the set up of your motor！
