vespa piaggio olympia M7 engine stud

olympia engine cylinder stud for all vespa piaggio mopeds and kinetic these are reinforced super vespa studs just like the original ones length = 120mm M7 thread

Word on the street is that these are the perfect size studs for Derbi pyramid reed and piston port engines. Sorry flat reed duders, these are a little too long for that application.
