    Welcome. Very nice looking machine.
    I guess you have tried the usual Suzuki parts, eg Robinsons Foundry, Crooks Suzuki or Suzuki old parts? Maybe Aliexpress will have some too. Are they the same as any other bike eg bore diameter, ring thickness? Have you looked at CMS in Netherlands?
    Here is some from Aliexpress. I use them with no problems.

    Are the GJ72A pistons the same size as the GJ71A?

    Webike list some bits.

    After finding they are 44mm pistons maybe four sets of these may work for you.
