Malossi Cylinder Head MMW 136 cc by MMW for POLINI 130cc for Vespa 90-125 / ​PV / ​ET3 / ​PK / ​S / ​XL / ​2

The MALOSSI 136cc Cylinder Head is the basis on which MMW and Worb5 both work to fit the POLINI 130cc.

Aluminium / Ø 57,5mm/ short thread/ with O-Ring,
Aluminum cylinder head, massive construction,
57.7 mm Ø, short thread,
compression 13.1 – 13.5:1,
squish band clearance 1.0 – 1.1 mm,
centred central combustion chamber,
high quality cast aluminum, with O-ring.

MMW updated this cylinder head to fit modern needs. The angle and width of the squish band clearance are modified, the spherical shape of every cylinder combustion area is optimised, the layout for these heads is made of many individually constructed items for ESC pilots. The feedback from many scooter pilots is collected and used. The heads are made for the MALOSSI 136cc, The POLINI 130cc and for GS pistons 130cc to be used in MALOSSI / POLINI / DR 130-136cc cylinders.
Higher performance, less pinking, increased durability. These are the positive results of these head tunings.

The head is constructed to enable a higher compression of 13.5:1 and an optimised squish band clearande of 1.0 mm. This makes the MALOSSI head measurably more stable and holds up to pressure better than the POLINI original.

Conclusion: A must have for all POLINI / MALOSSI pilots.
