Includes two separate STLs for riders and sidecar gunners, separate STLs for the bike and sidecar, as well as some extra storage gubbins. You can either assemble bikes out of these separate bits or use my pre-exported example STLs.
I have kept as many parts separate as I can so you can assemble bikes per your own desires in Blender/your slicer.
You've two types of each rider, a separate bike, sidecar and some storage options to tack on. Please look at my included .LYT files for examples (opened in LycheeSlicer).
Alternatively, you can use my pre-exported merged STLs.
