Description
Located within the cylinder body and crankcase, the 2-Stroke Piston #4 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 50mm diameter and 10mm skirt, this piston is compatible with a wide variety of 2-stroke engines.
Compatible with the 66/80cc BBR Tuning Bullet Train Electric Start Engine and most Grubee Skyhawk Bicycle Engine Kits
