Hey y'all. New motorcycle rider here, and just bought a 1980 Suzuki GS1000L, and I noticed something sort of annoying. The frame AND engine do not have a typical 17-digit VIN number. On the badge on the front of the frame, where the VIN should be (and the badge even says VIN on it before this comes up), it instead has the following. GS100G-702xxx The engine also has one of these numbers, though it's slightly different. GS100G-107xxx. What does this mean?? Why don't I have a typical 17-digit VIN? I've been scouring online for anything mentioning this, and there's nothing that mentions this. I'll also say that the GS100G-702xxx is not only on the badge, but also machine-etched onto the frame, just below the badge. I'm very confused what this is all about, and would love some help on this. Thank y'all!
