I think it's restorable but will take a little more work than usual to re-weld the tail and a new set of rear peg holders. I wonder about the frame though....the S/N is a Z1B but when I look at the front brace I don't see the bolt holes for an oil cooler. That front wheel is from a later model.
I have several restored bikes along with a 2006 Goldwing with a sidecar. My wife has a 2019 Suzuki DR 650 for on and off road.
