Product Description
Brand new official Piaggio Group factory complete crankshaft assembly designed for legendary liquid-cooled two-stroke 50cc geared motorcycle platforms. Forged and dynamically balanced to strict Italian metallurgical and rotational tolerances, engineered to eliminate high-RPM vibration, maintain primary gear alignment, and ensure maximum bottom-end reliability during a complete engine rebuild.
Vehicle Compatibility
Engineered explicitly for Derbi and Piaggio liquid-cooled two-stroke 50cc geared platforms (utilizing the high-performance EBE / EBS / D50B0-related engine eras depending on exact production years).

Fitment & Technical Details
Inspect main bearing seats, oil seal journals, and flywheel woodruff keyways for absolute cleanliness prior to assembly. Warm the aluminum crankcase halves evenly and press the new crankshaft assembly squarely into position without side-loading or hammering directly on the threaded shaft ends.Verification: Crankshaft spins freely with zero binding, axial play, or radial runout inside the matched crankcase halves, providing smooth primary rotation for high-output two-stroke operation.
