Modern Vespa

Do you follow this maintenance schedule

First PMS is 1000km or 1 month, change oil.
at 5,000km or every 5 months, inspect only
at 10,000 or every 10 months, change oil, drive belts etc.

Nope!

There is obviously an error in this edition of the workshop manual.
In all other versions known to me, it says "km" or "miles" at this point (whereby the miles are given in brackets).
In addition, there are two columns for the time interval of 12 or 24 months.

Correct is 1000km, 5000km, 10000km, 15000km or every 12 months, whichever comes first. Also change the brake fluid every 24 months.

Please tell us the year of manufacture of your Vespa, then we will post the correct information with source.

The version you have linked applies to a PV 150 from 2016 and, as stated above, is incorrect.

This is what I use for my 2022 Primavera 150. I think all Primavera/Sprint 150 from 2014-present would follow the same.

Follow the sched in the user manual that came with *your* Vespa
