TNT Tuning piston kit for Peugeot 50cc scooters.

Fits standard 50cc cylinders.

NOTE: 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 (click here) instead of this one.
The Taiwanese pistons are 39.95mm across the bottom of the skirts (perpendicular to the gudgeon pin) the Italian ones are 39.85mm
