Description
Super Compression Crankshaft for Piaggio 50cc 2T Scooters
The CM SUPER COMPETITION – HPC – racing shaft is manufactured to the highest standards. The Red -Pads- are made of a high tech polymer and are used to increase the pre-compression (and thus to better fill the cylinder with highly ignitable mixture). The connecting rod is fitted with SSC race bearings at both ends and is also polished.
