TUNING ROAD – for everyday use Product description
MWW
modifies the
MALOSSI
166cc cylinder head to deliver a perfectly adjusted cylinder. The angle and width of the head squish band clearance are modified, the top is adjusted to each individual race cylinder. This creates a new head layout, promising more power, less pinking and increased durability.
The
MMW
head for the
POLINI/D.R./PINASCO cast iron 177
has become a classic part especially appreciated by Vespa fans who drive their POLINI long distances. The
MALOSSI 166
head has a higher compression and is much sportier than the original. The PINASCO 177 has lower compression and less extreme port timings. The new
PINASCO 177 MMW head
together with the 1.0 mm base gasket included in delivery can give your cylinder a jump start to more power.
All heads are available for standard 57mm and long stroke 60mm. 60mm heads will not need additional gaskets.
Conclusion:
MMW makes 166/177cc tuning more effective and durable.
