I went and looked up the motorcycle in Kino's Journey after a random post reminded me it existed. While the specific model is unknown, the Brough Superior SS100 motorcycle that Kino rides currently sells at auction for between 300,000-500,000$.
Meanwhile over in WW2 militaria land, the kettenkrad half-track that Chi and Yuuri drive in Girls' Last Tour currently sells for around 130,000$.
Alas...
(sidenote: I'm very tickled at how "girls exploring apocalyptic landscapes on cool vehicles" sort of became its own niche manga subgenre. I gotta check my copies of Yokohama Shopping Log and Touring the Apocalypse and see what the bike/moped in that are)
