Vespa Sprint Veloce, P/PX125, P/PXP150 - Malossi 166

Malossi 166

Click here for a .pdf version of Malossi's instruction manual.

Malossi's installation instructions (above) are pretty goofy but a good place to start. Here are the basic specs:

Timing 18 degrees BTDC
Bore 61mm
Stoke 57mm (standard)
Compression 11:1
Capacity 167cc
Main Jet 115 (SI 24/24)

This kit slightly increases the standard three port 125cc/150cc engine first introduced with the Sprint Veloce and still in production in the PX125. The port layout is different and to work effectively the casing mouth transfers have to be matched to the barrel.
