320mm oversized rotors

Hi,
I have ordered calipers (with custom bracket) that fit only 320mm rotors.
Is somebody aware where i could get oversized rotors for my gpz 750 1982?

Have a nice day!
Thanks,
Laurent

Look here:(Not sure anyone can supply the 320's you need,but ask).

Your best bet would be from the place that you got the calipers and brackets from.
I would imagine that they would also sell the discs to use with their oversize brake kits.

Here's one of mine
6 pistons, 310mm discs, 76 KZ 900

I Have a similar problem but at a different point. I need the mounting plates that adapt one type of caliper to the fork mount. Anyone know who has a selection of those, before I start cutting my own. I am trying to adapt zr750 calipers to "J" forks with ST oversize rotors. I need to move the calipers farther out and up and the bolt spread is a bit larger. something almost the same if NOT the same as in the preceding picture.

Makes ya wish that Sandy Klaus came early this tear doesnt it.bj

It would probably be wisest to get the disc from the person that you got the "kit" from.
There are a lot of mfg's that have 320mm discs. Most of them have different offsets than the others and "stumbling" across an exact fitting disc would be "wishful thinking".

I haven't found a bolt on 4 bolt brake disc in 320mm that will bolt directly on to the KZ wheel. The discs usually need to be modified to fit the application that I am putting them on.

I believe that EBC will custom make a disc for you.

I've bought the calipers from a kawa Z1000 2005 which are Nissin and are for 320 mm rotors.
My original calipers are FUBAR (cracked).

Since i have access to a waterjet cutting machine i'll be designing my own brackets.

That's why i'm asking where you get these rotors?


Kind Regards,

I get the discs where ever I can (ebay, swap meets, yard sales) and I often buy them brand new.

It would probably be best to get some custom made discs through EBC. Most motorcycle shops can get them.

When I get discs for my kits, what they are and what they fit doesn't really matter much. What matters the most is " Can I modify them to fit what I am working on ?". All of my kits come with modified discs(discs that were modified to fit a particular application and will ONLY fit that particular application).

I am not aware of a bolt on 320mm disc for the KZ wheel. Custom made may be your only option. There are very few 4 bolt brake disc made for the KZ and they are usually OEM style replacements(Stock size).

ive got a machinist who offered to make some billet front hubs that will use stock bearings and spokes,but i need to figure out which rotors to use for him to make mounting holes for them.
are there any big rotors with offset close to stock kz rotors?

JMO,
If you are custom making a hub, you can have it made to work with any brake disc you want.

Another JMO,
If you are making a hub, I can't see the advantage of making a (dimensionally) identical hub to one that is already offered (stock KZ). Custom make a hub to work with a disc and factor in the (disc)offset in the fabrication of the hub.

The old (KZ) discs are what are considered wide band rotors. They use the height of the brake pad to contact the "wide band" of the rotors. The newer discs are considered narrow band rotors. The use the width (front to rear)of the brake pads to contact the rotor.
Using a narrow band disc(newer disc) with a wide band (stock KZ) caliper usually have the brake pad contacting the buttons on the rotors. I would strongly advise against cutting the brake pads for clearance (they may contact the buttons when the pad wears down). I have seen 1 person do it on the CB 750 message board, and(a 3rd JMO) is a disaster waiting to happen.
