I think you're in the year range of the 650 r shock. I'll have to go back and look but the 650r shock will go in upside and you'll need to make spacers for the lower mount. Works fines, a little bouncy but it raises it up an inch and allows the bike to steer a whole lot better $
This shock the Jesse Norton offers at yamahar3racing.com is what I ran the following year. Traxxion drop ins, and the R6 shock. For this shock, you have to do some cutting to the subframe. It worked really well!
I really like the fz and I wish I could afford to have a street and track bike. But I can’t, and honestly living here in Florida makes street riding super boring so I barely ride anymore.
