Wanted to ask this already for some time. My 2004 GT has now 6500 miles on it. When I was close to 6000, I called up Vespa Seattle Service and wanted to schedule an appointment since in the Vespa service booklet 6000 miles would be the next official service.
However Vespa Seattle told me that that had changed and now they recommend coming in the next time with 8000 miles not 6000 miles. I confirmed with the service dude that this would not void the warranty. Has anybody else heard the same??
