Bolts on with 3. My bike's an NC23 Tri-Arm for reference.

Same diameter but bolts on with 4 bolts on the nc29. That disc is the same as:
CBR400 NC29 GULLARM RRL/RRN/RRR 1990-1994
CB600 HORNET FW/FX/FY/F2Y/F2/F3/F4/F5/F6 1998 -2006
CBR600 ALL F MODELS 1991-2007
CBR600RR 2005 - 2008
CBR900RR FIREBLADE 1992-2003
CBR1000RR FIREBLADE 2004-2008
VTR1000 SPY/SP1/SP2 2000 - 2007
VTR1000 F FIRESTORM 1997-2006

and maybe more.

hmmm yes.

It's to fit a NC29 rear wheel to a FZR
I'll probably need to get the caliper carrier remade rather than a special disc

What diameter did you need?

CB-1 discs are 240mm if it helps.

Maybe you can make an adapter to fit your disc to that wheel?

Careful as the CBR hub is quite big, have you checked if your carrier as-is clears the hub?

I haven't fitted anything up yet - the hub is 182mm and mine is 186mm although the rim's 1/2" wider.

The FZR disc is 210mm dia, so I need an extra 5mm for the CBR disc ... I'll try to stretch the carriers bolt holes to begin with. I'd imagine the caliper will need to move in or out along the spindle.

Please don't, that's going to fuck the whole lot up. Consider how it actually works before you do that. I've had a rear caliper that'd opened out those holes on its own, not even by much but the whole thing wobbled and didn't work right, had to replace it with a good one.

Custom carrier, or custom disc, or some sort of "proper" mod, don't muck about with brakes!
