Hm? I thought its already mounted in the FZR 600s Frame....waht doesn´t fit then with this Swing Arm? Perhaps needing an offset Frontsprocket? Or was the question about what else might be possible to modify at a 600?
If it was the last point your question was targeting, then perhaps a modification for a Seatexchange against a Cagiva Mito or a Streetfighter-Style Seat (like from
http://www.mgm-bikes.de for example) or something else might be interesting?
For most of the usual Seatmods you will need to cut the Rear-/Subframe a little bit and will have to construct a supporting Frame yourself for proper mounting the seat, where the additional selfconstructed Rearframe supporting part will either have to be welded to the cutted Rearframe or has to be fixated on it with some Screws ...some guys here in Germany did this with their FZR 600s, YZF 750s, FZR 1000s and so on
Just have a look to the link given before and to one of the most-famous magazines here in germany for this kind of custom-bikes, Fighters-Magazin, at
http://www.fighters-magazin.de/fm/ for getting some Ideas
