Blimey. New discs on a Fazer? I've got 92k up and they're still within service limits.
I've just stuck some EBCs on my other bike and 4k miles up and they're doing fine. I went for the EBC XC series with the clever oblong button rivet mounting which supposedly prevents warping. Got them from Demon Tweaks. Not as cheap as Armstrongs, but not that much more expensive and certainly cheaper than Galfer, PFM, Brembo etc. Cheap Chinese stuff - I dunno. I did a lot of research trying to get the best bang for my buck and not all of the chinese discs were horror stories. But then again, some did have the rivets coming loose and so on.
Only problem with EBCs is they say using non EBC pads invalidates the warranty. I wonder how that would stand up in court though. I suspect it wouldn't.
But Fazer discs are the same as early R1 and FJR discs, I believe, and there's shedloads of second hand ones on eBay. £100 quid should net you a pair.
