Product description

Harald Grillhiesl is the boss of the small tuning shop, MMW. He has made a name for himself producing tuning cylinder heads on the mainland European scene. Hardly anyone knows their way around squish bands, compression ratios and combustion chambers like he does. The MMW cylinder heads are produced precisely engineered, with exact angles and a very clean gasket surface area. Years of experience, modifying hundreds -if not thousands- of cylinder heads, is shown in the obvious high quality of these items.

The basis for the PX200 MMW cylinder head is the standard original PIAGGIO part. The combustion chamber is re-milled with a CNC process and so receives a new profile layout. This is designed for an improved relation to the shape of the piston crown, as well as a better fit to the following cylinders bore diameters: MALOSSI Road and Race, POLINI, PINASCO, POLOSSI, and the original PIAGGIO cylinder. We also have long stroke crankshaft cylinder heads available for most cylinder kits so eliminating the need for time consuming experimentation with varying gasket thickness's. Consequently an ideal cylinder head is available for virtually all motor setups. Some come supplied with an O-ring gasket as necessary. Knocking and pinking, those dreaded sounds announcing an imminent heat seizure or worse, is eliminated with the use of this cylinder head model. That is, if the reason for your seizure was an incorrect compression ratio...

Conclusion: Higher performance, knocking and pinking eliminated and a more enduring motor, what more could you wish for?

 

Aluminium construction/ diameter 68.5-69.5mm/ 57-60mm stroke compatible/ long spark plug thread/ O-ring gasket as per kit

Aluminium, CNC milled combustion chamber, long spark plug thread, squish band 0.0-1.3mm, compression ratios between 1:10.5 – 1:12, O-ring as necessary

 

SIP-TIP: Do not forget to order new spark plugs, base and head gaskets as well as pack-up plates to fit this cylinder head kit.

 

This cylinder head is ideal for motor performance enhancement projects that include the standard OE PIAGGIO 200cc cylinder.

In the standard barrel/piston setup there is a gap of about 1.8mm between the top edge of the piston and the end of the cylinder bore when the piston is at Top Dead Centre (TDC). The MALOSSI and POLINI setups have a similar 'built in' squish band clearance. This automatic squish band clearance that the 1.8mm clearance at the top of the piston provides, enables the use of a cylinder head without a squish band recess, to be made possible. If you are including a crankshaft with a longer stroke of 60mm, this squish clearance will shrink to 0.3mm. Providing the barrel you are using has an adequately low port timing you can use a cylinder base gasket surface pack-up plate with a thickness of 1mm to restore a more healthy squish band clearance of 1.3mm.

57mm stroke: without extra gaskets or spacers has a squish band clearance of approximately 1.8mm

60mm stroke: with a base gasket surface spacer of 1mm in thickness has a squish band clearance of approximately 1.3mm
