    Default 900RR USD Fork Swap_Bits and Bobs Qs

    I have recently posted to the last full-featured thread on the topic (LOCATED HERE) to no replies, so I thought I'd try again here. Apologies to those of you who have seen loads of threads on this. I have as well, but data/info falls short on the small but necessary parts.

    In the former thread, lambchops breaks it down as follows: "You can swap the frontend from a 929 or 954 right over, I used 929 yokes then cbr1000rr 2005 forks within those yokes and it all works great. Advantage with 1000rr forks is you get the radial calipers."

    So far, I have acquired all of my parts based on that thread:
    * TOP YOLK for 929
    * RC51 sp1 front wheel
    * CBR 929 lower triple and stem
    * CBR 929 front wave rotors
    * CBR 1000RR forks (04-07)
    * CBR 1000RR fork seal kit
    * CBR 1000RR front fender
    * R6 Monoblock calipers
    * SS brake lines

    I'm hoping someone might be able to direct me in terms of bearings, spacers, collars, etc. Needing to clarify the following:
    * Which steering stem bearings am I looking for (cbr900 head bearings)?
    * Which wheel bearings/collars am I looking for?
    * Which axel should I be using (RC51, 929)?
    * Anyone do this setup or could guess on spacer/collars machined to center the hub?
    * Anyone so this setup or could guess on spacer/collars machined to center rotors in the forks/calipers?

    THANKS FOR TAKING THE TIME TO READ AND ADVISE!!! Was hoping to attached a few images of my projects bikes, but I do not yet have permission to do so.

    How did you get on with this in the end? I'm at a similar stage now and I've done the same shopping as you apart from the front mudguard (fender). Happy to share my experiences if you're still at the prep stage. I've got a 99 RR-X

    Quick update in case you're interested

    CBR1000rr forks have arrived and they're absolutely mint, can't wait to get them fitted. I've now got:

    Both fork legs, plus 929 upper and lower yokes
    Both calipers and a seal kit for a rebuild, plus new pads of course
    New caliper bolts (they're hollow! Weight reduction right there)
    Front axle, wheel and spacers
    Front brake discs and new mounting bolts
    Very shiny carbon mudguard from the Carbon King plus all the mounting bits and bobs
    A new tyre (went for a Metzeler Sportec M3 as it's what's on the rear. Will swap for M7RR when it's time)
    929 Clipons
    New front wheel bearings and dust seals

    All going on in about a week's time once I have the wheel and top yoke powder coated

    Well, I have replaced my RRW front end with a 2006 (I think it was) inverted set from a 600RR. I won't be able to see how it responds until this summer.

    Wish me luck.
