Hi guys! I have just bought a "new" 1989 CBR600F, it has a rather worn rear tyre which is a 150/70 17, I understand that standard is 130/80 17, but I just want to make sure that the rear wheel has not been swapped out for a later model or anything like that. So could someone please measure the rim width for me and post it on here? Thanks!

 

Rear wheel is 3.5 inches wide
