RR model --- https://www.ebay.com/itm/1994-Yamaha-FZR400RR-SP-3TJ7-/143523303508?_trksid=p2385738.m4383.l4275.c10
The swingarm and forks do look to be genuine SP items.
That's gonna go for big bux.
I've been watching that for quite a while (and the seller's other bikes for the past few years). He has some really nice stuff, and a lot of it! It's been listed 3-4 times in the past few months, starting at $9K.
Price seems reasonable to me.
Makes me wonder what my 92 FZR 400 RR (non sp) is worth? It's every bit as nice as that one!
I will tell you: it is worth KEEPING. Only under the most dire circumstances should you ever consider selling it (to me, of course!).
