Welcome to the forum, great advice on here to keep your bike running.
Maybe its a US import? Do as Nurse Julie says and check the manufacturer date against the log book as a good starting point.
If you post some photos there will be plenty of advise on here of where it may have come from.
Tip, I think you need to have 5 posts before you can add photos (stops the spamming community trying to sell us life insurance!).
