I am currently building an OW01 for circuit racing, the class demands 43mm or period USD. I am going RWU 43mm. I was looking for opinions, expirances and any relevant info with the forks I have avalible. GSXR1100K 1989 XjR1300SP 1999 YZF R6 2001 FZR400rr sp. Cheers

Early R6 Nobby.  The only real difference is they have different caliper spacing suited to different spaced calipers.  Xjr1300 have the same lowers, but much longer fork legs so I wouldn't use them.  

I think the 04 onwards R6 fork had 2 axle pinch bolts, so probably not a good choice, but one of the best conventional forks ever built.

I think the Sp 400 forks where also 298mm .  Drop in when you are in melbourne.  I've got all of the forks here to look at.  Cheers :-)  and some ideas :-)

Yes Knobby, send a text when you are close.  The early R6 (single pinch bolt,fork) I think you can get away with using the OW caliper (similar to the suzuki bandit but magnesium) removing the botton mount and welding in a new lower.  Haven't quite got to the definitive answer stage, but looks promising.  Will be good to catch up :-)  

Without mods, run a 298mm TZ or the like disc (kawasaki are the same spacing), Ducati 3 spoke 916 bembo wheel,  and a TRX or the like brembo goldline, 100mm spacing caliper? 

Possibilities are endless.
