I am so glad I found this forum as I have been doing my head in trying to fit a zxr400 wheel into my honda.

What I need to do is change the rear pitch 520 to 530.

I have a zxr400 1995 wheel.

I have so far found that a zxr750 r has a 530 and a zzr400k has a 530.

Does anyone know if the sproket bolt fitment would work or would i need the whole cush drive and if so would the cush fit.

I can do or can get done minor engineering so if its yes the bolt centres are correct but the centre hole is wrong then thats easy etc

I have tried to find details of the sproket bolt sizes but drawn a blank.

Many thanks for your assistance.

this is a wonderful website for all things sprockets...
http://www.jtsprockets.com/catalogue

ZXR400 L models are 104mm mounting point center to center, 80mm central hole, and a 10.5mm mounting hole (520 pitch).

ZZR400k is too big (140mm center to center)

well done though, as...
Kawasaki ZXR750 R L1-L3 will fit as will any of these (aparently):
http://www.jtsprockets.com/catalogue/sprocket/JTR478
http://www.jtsprockets.com/catalogue/sprocket/JTR488

if you find a suitable one for sale (ebay etc...) ask the seller to confirm the dimensions first before you buy.

Thank you for the speedy and efficient reply. I had measured my sprocket but couldnt find the site that you linked me too. Thats the sprocket sorted.
next on the list is a rear caliper and bracket and a set of front ones and will be using this forum to find upgrades and other bits and bobs.

Many thanks again.

if you want, you can do the gsxr1000 rear caliper mod that ive got on zxr400world...i would give you the link, but i got banned last week for suggesting that one of the mods was both inbred and suffering from tertiary syphilis - we have a good relationship like that, this makes it the second time of being banned from there :D

its really easy if you have a dremell, you just need to take a few mm off where the caliper bolts to the hanger...and gsxr 1000 K1-3 brakes are newer and cheaper than 20 year old zxr ones and look identical. it has a bit more stopping power, you will lock the rear wheel if you stomp on it too much.

Just put a spanner in the works for the rear caliper. My swingarm has a top mounted torque arm.
There is always a plan b so time to put that in to action.
what the bolt spacing of a rear caliper please?

ill check tonight if i remember :D

Plan c already.

Will cut the bracket off and re mount on bottom of swingarm.

Now on the lookout for a gsxr 1000K1 rear caliper, bracket and torque arm.

The most of it is getting blasted and powdercoated so thought why not.

i dont know if the gsxr1000 k1 bracket is a good idea.

if you are using a zxr400 wheel (and i assume spindle) use the zxr400 rear caliper bracket (shave the sides down or get spacers made accordingly so it fits the swingarm) with a gsxr1000 k1-k3 rear brake, and get a torque arm made (an engineering firm will knock you one up, its only steel/aluminium rod/bar) or use the one that was on there originally if you are getting the mounting point changed...

I was half a step ahead so went for standard zxr400 set up.

will post some before and after pics once I get weaving on this project.

cb900fb with 400 front and rears.

cheers
