Cylinder head -MMW Malossi 172 cc (66,0mm)- Vespa T5 125cc

MMW cylinder head T5 for 172 cc Malossi cylinder Ø=66mm.
Absolute high-tech cylinder head CNC milled from the full aluminium block. Therefore the head is very massive and solid. This is very good for the noise development. But you have to take care that there are small rubber pieces between the cooling fins, like on the standard head, to absorb the vibrations and therefore the disturbing noises. The larger surface of the cooling fins is also much better for cooling.
The combustion chamber is designed for maximum efficiency. The highest torque and performance values paired with increased reliability are by no means mutually exclusive. On the contrary, there is a much better turbulence and more controlled combustion, which may even allow experiments with the ignition timing.
