I need a pair of Yamaha discs with the largest off set possible, 6 bolt fixing and the centre hole is 64mm, 296 mm diameter, most older yam discs kind of size.
Or what can I get with a mahoosive off set?

Most of the Yam discs are going to be 10mm, it's a standard for Yamaha and Ducati.

You can get offset spacers that go behind the discs like Mini wheel spacers when you fit bigger wheels or rear brake drums, Kayla has some. I don't know how thick you can go though.
Some companies will make special discs up, Brembo can be made by Mode Performance in Silvestone ... expect to pay £350 though.

Or use a different wheel with a wider hub.

Or space the calliper mounts with a bracket - probably the cheapest solution.

Thanks Boris
I need something like 23mm in total from wheel hub to caliper slot!
I have R6 yokes with CBR forks and a Yamaha twin disc spoked wheel to match up (remember my XV 750 cafe racer project?)
I've spoken to Kayla and she can make me a set of spacers but I'd like to keep the spacers as thin as possible by finding the largest off set discs I can. I have a standard XV 750 disc that has 13mm off set and I don't think I've seen anything else with more than that, BUT I do still have to space the calipers too as they need to clear the wheel spokes.
Lots of juggling measurements...

Use R6 forks

I actually have a set for sale that came with the yokes but I wanted to fit the as new set of Showa forks I have.
Yeah I like to make things difficult!

Yeah ... but that's a bit close to pi**ing in the wind

True but the yokes are in with new bearings and small frame mod, the forks are a straight fit , the wheel and spacers are done, it's just setting the gap between spokes and calipers then some measurements for the disc and caliper spacing.

Who mentioned project 660?.....

It will take a long time to go through, I know I did it when I fitted yzf forks to my gsf4 but if you go onto the metal gear brake site they list all discs complete with pcd offset etc. Some of the older gsxr's have large offsets, around 20mm but 23 mm is pushing it.

Thanks VVS that's a very handy site.

What about an FZR1000 EXUP/RU front wheel? They have a slightly wider hub so you might not need quite so much disc offset?
