Located within the cylinder, the 100cc 2-Stroke Piston is a crucial Bicycle engine component. Connected to a connecting rod, this part moves in response to engine combustion. The result is crank movement from the transfer of force created from combustion that ultimately propels your bike.

Compatible with V1 and V2 80/100cc Engine Kits
Got this to replace a piston that grenaded inside the jug. Just awesome performance.
The original 3 ring piston that came in the engine was of much lower quality than the replacement with 2 rings, also sits in the cylinder tighter than the old one.
