Articles I have read suggest in the neighborhood of 30mm of sag is best. At that setting, you would have to be very careful going over the more well fed coppers.........

Thanks TexasKZ ,a very interesting article. Looks like Im going to be jumping into the world of suspension.

Ok that gives me A LOT to think about hehe. That is definitely a lot of help for me really. Maybe it can become a 3into1 easily but I really hope not.

My forks are only 720mm so that's 4cm shorter! I'm thinking about finding zx9r forks since they seem to be the longest usd's around. I don't have a collector box either for the exhaust system so I might have some more play. I have to double check.

That is a very interesting article TexasKZ I guess I'll be jumping into the world of suspension as well

You should really look around for this list of fork lengths. Its in here somewhere but I dont know where.There may be longer upsydupsys than the ZXRs. Now is the time to find out before you get too far along.

Yup I still have to dig into that a little more to make sure. I already found a few lists, but mainly about suzuki's. There it's the TL which is the longest, but I think still 2 cm shorter than the zx9r. Untill now those are the longest forks I've found numbers of. except ktm, bmw etc, but those are too long. It might take a while before I find the right ones

Im looking for the list of fork lengths,I must have it somewhere and Im curious now.
I did find this www.caferacer.net/forum/project-builds/1...onversion-chart.html which might also be interestig for you.

Found this at ZRXOA

ZRX1100 766mm (30,15'')
ZX10R 06-07 743mm (29,25'')
ZX10R 04-05 730mm (28,75'')
ZX14 742mm (29,25'')
ZX636 750mm (29,5'')
ZX9r B4 94-97 766mm (30,15'')

I have a set of the zx9r forks in my rafters, they are indeed plenty long and there's mods you can do to the top tree to gain another 3/4" or so. One of the members here had details on that in his build thread

Any idea who? Im curious as I was talking with someone about it today and Ive seen the stepped triple trees but how would you 'mod' a triple tree?

I think it's mark1112 or some username like that? The top bolt on the zx9r is recessed, he had that area cut out, and a plate welded flush with the top of the tree, allowing the top clamp to be dropped 3/4" or so, effectively lengthening the forks, and using the stock triples

Here it is, post by mark1122

Floivanus,Huge thanks.I never would have found that thread. Its a very smart idea. Every little bit counts. Great.

Huge thanks from me as well. That is a very cool and simple mod that I would never have thought off.

With that mod the usds come close to the stock length.

That is indeed a nice list davido. Usually I check allballs their conversion chart which comes in handy too. You can find it on their website. Allballs fork conversion But they don't include stem length etc.

Ok, I have a full zx7r front from the year 97-03. I was lucky to find it, but I doubt I'll find a full zx9r front end that easily. So now I'll go research and see if the forks are interchangeable, then I can use the zx7r brakes, triples, wheel, with the zx9r forks. It will be easier just finding forks, than a full front end.

Have a look here

There are a few ZX9s up for slooping. Worth giving them a call
Or keep an eye on this page
www.marktplaats.nl/z.html?query=zx9r&cat...2022&postcode=1019MC
and see if anything comes up.
There are a couple of slooperijs advertising from Belgium.I bought mine from a guy in the south of Holland. You might get lucky and find something near to you.
Good luck.
