It doesn't always have to be a new Cylinder..
Once a Cylinder has covered a few thousand kilometers, it is essential to replace the Piston Rings or even the Piston in order to continue to ensure reasonable compression. We have the most important spare and wear parts for all common tuning and original cylinders in stock for you: i.e. Pistons, Piston Rings, Piston Pins, Gudgeon Pin Retaining Rings and Gasket Sets.
For older models we are offering pistons up to 5. oversize (os). This gives you the possibility to freshen up your older cylinders. The bore Ø always includes the size of the cylinder.
Our first choice in piston stuff is METEOR. METEOR pistons are first class quality. The GRAND-SPORT pistons are also made at METEOR.
In the PIAGGIO VINTAGE series, most of the pistons offered that are not made by PIAGGIO themselves is from GOL, Italy. GOL also offers oversizes in 0.2 mm steps. The quality is reliable.
Most pistons are outfitted with 2 normal piston rings (2xN) in 2.5 mm sizes (small frames 2.0 mm). With newer models, the upper piston ring is an L-piston ring. Older Vespas have baffled pistons, newer models have piston windows with curved piston floors.
SIP-TIP: install piston rings carefully, do not stretch too far, due to possible breakage. Pay attention to piston ring stop play, type and model. Trapeze rings have only one installation direction!
