Collection: Piston

Whether you are freshening up a tired top end or matching a rebored cylinder, this section links to complete pistons and piston rings for vintage Vespa engines. We cover largeframes from the VNB and VBB through the Sprint, Rally, P125X, P150X and P200E, plus smallframes such as the 50 Special, Primavera and ET3. Measure your bore before ordering, since pistons and rings come in standard and oversize steps, and fit new rings whenever you fit a new piston.
