Italian replacement piston for Peugeot 50cc 2-stroke scooters.

Fits both liquid cooled and air cooled 50cc standard cylinders.

NOTE: The Taiwanese cylinder kits (nearly all of the aftermarket 50cc cylinder kits) use a very slightly bigger piston than the original genuine standard Speedfight piston.
If you have an original genuine Speedfight cylinder you *must* use the Italian piston kit.
The Taiwanese pistons are 39.95mm across the bottom of the skirts (perpendicular to the gudgeon pin) the Italian ones are 39.85mm
