F4 rotors fit?

I recall coming across a post that included the CBR600F4 (NOT the F4i) as being a potential donor-bike for front rotors. I believe the 96-97 900RR and 94-97 VFR750 were included on the list as well as all F3s (exact same p/n). I may be able to line up a good deal on a pair of F4 rotors and want to be sure they fit before I fork over the money.

cheers

From what I am finding, the F4 (not i) rotors will not work.. But this is just from googling, I am sure others know for sure.

edit: http://www.fireblades.org/forums/hon...wheel-not.html

"According to my EBC catalog (available online):
CBR600F3 rotors are interchangable with 95-97 CBR900RR rotors (also 94-97 VFR750 and all VTR1000F)
The 98-05 VFR800 (non-ABS) and CBR600 F4 (NOT F4i) uses the same rotor as the 93-94 CBR900RR"

thanks. It seems the F4 wheel will not fit. Better to know before than after

600F3 wheels and rotors fit. F4 - not sure - don't think so. F4i definitely not.

F4 rotors are the same as the F4i.

Odd... I cross referenced the part numbers at ronayers.com and it showed that they use the same rotors from 99 up.

edit; I just checked aftermarket part numbers... different. Damn Ron Ayers.

Nope. I know for a fact f4i rotors are different than f4. I purchased a pair and the bolt holes did not match up with my f4 wheels.

Then something was wrong with one or the other. The F4 and F4i front wheels are identical.

Well I know the extra rims I got are from a f4. I bought a set of rotors off ebay. They were advertised as f4 rotors. They did not fit. Bolt holes did not match up. When I sent the guy a email he then stated they were from a f4i. Any ways I sent them back bought another pair and they did fit. Maybe they were not even f4i's.

Okay you guys got me thinking so I had to check. I checked wheels from a 2000 f4 and rotors and then 2004 f4i wheels and rotors. I own a 2000 f4. They are different. They have different part numbers.

according to EBC's Pdf file I downloaded, the f4 rotors aren't the same.
the 83-86 vfr's are though. But the 900rr's and the 94-97 vfr's model # are very close so maybe its a thickness or a small diameter difference?

Well, they are both 296mm so the only difference between them and VTR rotors would be offset.

.....and the mounting. The F4 and F4i rotors mounting pattern is different from the VTR/VFR750/CBRF3/900RR rotors.

Jamie, as you running CBR1100XX rotors (which model year? or does it matter?) on your VTR front wheel, I can assume it mounts up in terms of bolt pattern. How does it compare in terms of offset to the stock VTR rotor?

cheers

Yes, the 97-98 CBR1100XX have the same mounting pattern as the stock VTR wheel. I didn't check the offset, all I wanted was rotors that lined up correctly with the Showa inverted forks I'm using, which they do. I can measure them if it would help.

If at some point you could compare the offset to the OEM units that would be great.

thanks again Jamie

alright, did some research and it seems the 1100XX rotors are said to be identical to RC45 rotors and thus very close to VTR except for the following:
- thickness (thicker; 5.5 mm vs 5.0)
- diameter: 310 mm vs 296 on VTR
- offset: 21.1 mm vs 17.2 on VTR

I had a F4 rotor and VTR rotor for a side by side comparison. They are the same diameter with the same offset but the inside diameter is different. The VTR is 59mm the F4 is 62mm. Thus, the bolt holes do not line up.

Now... about those XX rotors.....

That doesn't sound right - the F4 rotors should have been 20mm larger in diameter.

Nope, both rotors are 296mm in diameter.

Need to revive this one for info

Getting ready to do the USD fork conversion, using a 929 tree set with rc51 leggs, am I understanding right here? Jamie, you converted and used your stock front wheel, just had to use rotor's from an CBR1100xx, did you have to change the bearings to fit the axle?

Jamie used GSXR forks. The CBR1100XX rotors are 310mm, the RC51 front end will require 320mm rotors. Your best bet is to use an RC51 front wheel and rotors.

Thanks Inde, yeah I hit up Jamies profile and started flipping through his threads and was thinking it looked like he used gixxer stuff. I was trying to stick with the three spoke to match the rear, there are a couple of decent looking 929/954 wheels on the bay, but, If it takes the rc51 stuff to not have any major hassles.. I can machine spacers and the like ya know.
Doing some more surfing under the guys who have swapped allready see what all I can dig up.
