The zx7r didnt change during the complianced 1995 - 2004 build period .. so you can race a 2004 if you want in Pre mod f1 @ pcra or in the unlimited retro at STG...these bikes are not yet log booked historic so there are quite a few mods you can do.

probably would just get a weld done on the swing arm - saves a lot of mucking around.
