Description: The BGM 52mm crankshaft is a plug-and-play replacement for original Piaggio 125/180cc 2-stroke crankshafts. No spacer plate needed – easy to install with the original cylinder head. Ideal for those seeking reliability and performance without additional modifications to the engine block.
Thanks to the 90 mm crank webs and 105 mm connecting rod, this crankshaft fits in both Hexagon/Skipper crankcases and Gilera Runner engine blocks.
