For a long time there was only the cast iron cylinder from Polini for the small large frame engines (PX, LML, Stella, Cosa 125-150ccm).
In contrast to the old version, this cylinder is made of aluminium with a coated raceway and therefore has the advantage of being more temperature resistant.
The overflow layout as well as the exhaust shape have been revised and the cylinder has been generally extended by a few modern gimmicks. The head is now screwed 8 times, a head gasket is added and is thus tight or can be mounted with little stress.
The exhaust has been given a 4-position steel flange and the spark plug can optionally be screwed in centrally instead of laterally.
