Located within the cylinder body and crankcase, the 2-Stroke Piston #5 is one of the most important engine components. Connected to a connecting rod, this part moves in response to engine combustion. This results in crank movement via the transfer of force generated and in turn propels your bike forward. Featuring a 49mm diameter and 5mm skirt, this piston is compatible with a wide variety of 2-stroke engines.

This piston fits most 66/80cc Flying Horse, Mega Motors, and RAW* engine kits.
