    I just came upon a free motorcycle and I have been having trouble identifying it. I've read around and have run into contradicting answers and no mention of a year so I was hoping you guys could help. I had seen a forum post on here roughly 6 months ago with a list of VIN numbers with corresponding model years but I haven't been able to find it again.

    Yep, it's an 81. To bad it's been all hacked up but for free:)

    What's your vin number? All sohc xs400's are 391cc motors. The cc's are stamped on the lower front part of the block. Post some pics of you bike.

    That would be a 79-F model.

    Similarly, I recently acquired either a 78, or a 79 model XS-400. Please advise. It has disc brakes front and rear, electric ignition (and kickstart), with cast wheels. VIN: 2LO- 101397

    Good to know. I just picked up a XS400 and the VIN started 2L0. I was told it was an 84 but when I started looking into it I figured it was late 70's. I called a few dealers and they couldn't look up these old 9 digit codes either.
