Are they?

I haven't seen them and they're a couple of hours of bad roads away to see if they fit.

is there anyone with knowledge on fittment compatablity?

As far as i know they are the same callipers as on the ZX7R, and i know for sure they wont fit the spacing is too large. If you want 6 pot callipers that fit, you need K1 gsxr calipers. They need to be modded however the details which im not 100%.

They wont fit no, as said there the same spaceing as the P zx7r whats quite abit diffrent,

if you want to upgrade the calipers eaither go for the zxr750 2pots (just a larger version of the 400) or the gsxr1000 K1/K2 calipers but you'll need some spacers made up.

I was looking for that thread cheers

You need to drill out the calliper mount holes dont you, and then fit those spacers in them holes? And you also use the gixxer callipers bolts too?

I didnt have to drill the mount holes no they just slide strate in (very snug!) but this is on the 750 (but as far as im aware the 400 sizing is the same?)

I had my own bolts made up out of Ti as i didnt get the standard bolts but id guess there to short anyway!
