Guten tag,
I have a Vespa P80X a few weeks now.
It runs very well and hits 80kmh (gps) quite easy.
So I was wondering if I had still the standard cylinder fitted or an upgraded cylinder.
It looks like the standard cylinder has a 46mm bore. (http://www.moped-museum.de/vespa/vespa-p80x.htm)
But when I measure my cylinder I get exactly 51mm.
The dr135 kit has a 60mm bore...
Are there replacement cylinders with a 51mm bore?
Thanks,
van Dijk
