It comes standard with 51mm stroke crankshafts and 97mm connecting rods but can also be fitted with longer stroke shafts and connecting rods.

Attention: To be mounted on Piaggio crankcases with stroke 51 and connecting rod 97 it is necessary to bore the cylinder mouth on the crankcase with a diameter of 64mm for a depth of approximately 8mm to allow the cylinder liner to enter the crankcase.

IT IS POSSIBLE TO DO THIS OPERATION WITH A MANUAL CUTTER USING THE STEEL GUIDE SUPPLIED WITH THE KIT BY SCREWING IT INTO THE CYLINDER STUD HOLES.

There is no need to remove the dust cover on the crankcase base.

Also fits flywheels with electric starter ring

When combined with the VMC Siluro Touring muffler, it becomes an engine with power always available while maintaining the reliability of the original engine with a classic look and sound.

The perfect tuning for your Vespa.
