CBR 1000RR HELP!!!

[970rr]

Could anyone with a 1000rr (2004-2005) tell me exactly the spacing of the front discs mounted on the front wheel?

And in case someone happens to have his 1000rr front wheel off the bike... could you let me know the exact lenght of the bushings and front wheel together?
(or said differently, the width of the bushings and front wheel bearings assy that fits between the forks - inside of fork to inside of fork).

I realy need this to fit the 1000rr front end to my 900 all the while keeping my nice front wheel!

Thanks in advance!

What, nobody has a 1000RR and a caliper? Inside of disc to disc - it's easy...

And also, anyone got a service manual or CD, I just need to rebuild the forks. Help would be greatly apreciated!

I thought we had a few 1000RR guys on here... :CONF Apparently they're all out riding their bikes. :D

Do we not have a service manual on here in our Downloads link above? I thought we did...?

Holy crap. We don't. I thought we did... Let me see if I can find you one.

I have one. Do you have an FTP site or anything? It's 103 MB... :(

Thanks for trying to help Jawhn!
I really just need the forks section... I gotta rebuild the ones I have ASAP.

Oh, I don't know what's an FTP site either... sorry.

All right... Let me see if I can edit the PDF down to just that section. PM me your email address, let's see if I can get this to ya. ;)

FTP site stands for File Transfer Protocol, basically it's a server where large files can be uploaded or downloaded to... :z So that means you don't. :EG

Let me see what I can do, here, but get me your email through Private Messaging.

Just chopped it down. Now it's only 8.2 MB. Get me your email and I'll send it to ya right now. ;) :V

[jawhn]

I just sent it to the email address you have in your profile. ;)

BIG KAHUNA: I have a 103MB copy of the 2004 1000RR Service Manual. You want to put it on here? How can I get it to ya? :z

Jawhn, you are the man!! Thanks a bunch!

And my thanks also to big kahuna, but all i need in the manual is the forks section.

You wouldn't happen to own a 1000rr and a caliper by any chance:D

[jawhn]

... You wouldn't happen to own a 1000rr and a caliper by any chance:D

Sure don't. Well, I have a caliper, but not a 1000RR :D That's why I'm trying to help you somehow... :rolleyes:

This site is mostly 900RRs, but we have a few 929ers and 954ers and 1000RRers...

Let me know when you get the PDF, I sent it a little while ago. Just the forks section. ;)

BK has a 1000RR... ;) But I doubt he's willing to take his forks apart to measure the bushings. Might be able to help you with the disc-to-disc measurement. :z

[ghbzorro]

Am I missing something? You have the 900RR forks, wheel, axle and spacers, you have the 1000RR forks, you have a caliper and you know arithmetic. You plan to use the 900RRwheel. What stops you from doing the math and determining your spacer requirements and (presumably) your brake caliper adapter dimensions?

Or have I misunderstood the problem?

Yeah Jawhn, I got it yeasterday, thanks a million!!!

Yep, you are missing a little something.

I do not have a 1000RR wheel, nor do I have the spacers. I plan to use my 900RR wheels (RC-30 actually) because they are magnesium. I do not want a stock 1000RR wheel.
But since I do not have these parts, how am I supposed to know how wide both bushings and the wheel are supposed to be? By measuring from inside one fork tube to inside the other... that;s no verry precise. I want to be within 0,005 in. The best way would be to just measure front wheel plus bushings mounted on just an axle.

And I need no adaptors for the calipers, I will be running 1998-99 brake discs (310mm like 1000RR 04), they just need to be wider apart by something like 0,100 in. aprox. But to make that shim that will sit between the wheel hub and the disc... I need a precise measure by vernier caliper.

That;s basically it.

BTW, if I can get a precise disc to disc - that;s awsome -. But there is no story about taking the forks off... just the wheel. And I do not ask that, I just think someday someone with a 1000RR will take off his front wheel himself to change a tire... and there! You can just measure left bushing + wheel + right bushing by mounting it on the axle. But I think I might have an idea as to how I could figure it out... Will be way more complicated though. thanks again.

Thanks for the clarification.

If I was in your shoes (and I am not :D) I think I would put more trust in my own measurement of the space between the forks on my actual bike than somebody else's measurement on theirs. The space between the forks on your bike will surely be different than the space between the forks on somebody else's bike. Only when you are working on your own bike's dimensions does manufacturing spacers to within 0.005" have any value.

In my opinion, manufacturing spacers that put the minimum unnecessary stress on the fork tubes and bushings should be your real target. Simply replicating the outside-of-spacer to outside-of-spacer dimension of somebody else's bike would still work OK, but would not be absolutely optimum.

Are you sure you want to shim the rotors out? I think I would prefer to make adjustment to the caliper position than to monkey around the rotors. In any case I would wait until I was ready to assemble. It is possible that there is enough space as is. If not then I wonder whether just making the rotors fully floating would do the trick???? Guess it depends on the amount of interference.

Hmmmm. Maybe using pre-warn pads would make enough of a difference :skep:

Hey man!
I see what you mean with measuring the fork to fork distance and all...
For the rotors, I don't have much choice. The 1000RR calipers are radial, that means moving them from left to right is almost impossible without changing the whole tripple clamp assy. They are easy to adapt to oversize discs though.
And no, there is not enough space between the rotors of the 900 to convert with 1000 forks. have to move them out. Making them full floating is a real hassle and would not change much, and pre-warn pads are out of the question. Right hand caliper pistons would be pushed way out while the left hand ones would be way inside... & I want new pads!
And moving the discs outwards doesn't cause such a problem: the bolts are stressed in shear not torsion. However, moving them out would induce a little bit of extra torsion stress on the bolts, but not nearly enough to start being worried. Especially if the shim sits verry flush to the hub and rotor, and if machining tolerances are verry close.

Its cool to see people interested... I've almost lost sleep over all this:o

[speedextreme]

This is just a thought to help you out "so to speak".

Put the forks onto the bike or even just in the tripples off the bike, and put the axle in. Once the axle is in, that takes care of any rotational forces on the fork tubes. Then what you do is mount the calipers without pads on the forks. NOW, take a straight ruler or even a micrometer and measure BOTH the outside to outside and inside to inside of the calipers. (Know what I mean) Then just take the difference between those two measurements and divide by two, subtract that number from the Out to Out measurement or add that number to the In to In measurement. ANd there you have it. Exactly centered measurement for your brake discs.

And another way is to do this, if you have everything that is. Put the assembly together loosely (except for the tripples to forks, tighten those), then put the wheel on with the rotors, put on the calipers with the pads and the pistons all the way pressed into the calipers. Then once it is all together, just "pump" the brake lever till the pistons push the pads against the discs, and you are done.

I have dealt with this type of thing before. And I do know what you are talking about. But it doesn't hurt to just try it first. If you have everything that is. If not, buy everything, and if it doesn't work out, sell everything.

Laters.

'sup man!

Yeah, I see what you mean. The only thing is that measuring stock disc to disc mounted on a wheel (which I do not have nor intend to buy) is pretty easy and straightforward. While your formula is not hard - so to speak - it allows for little discrepencies to be added to one another and leaves you with a mesure a little less precise.

However, the disc to disc space is not the measure that needs to be so ultra precise as the pistons in the calipers should easily compensate for being 0,010 in. off, let's say. Probably more...
I'm just used to working with small tolerances.. it's like a reflex to go for the exact measure.

Anhow, thanks for the interest, any help is apreciated.
