    No pun intended I assume :lol3
    I did, but mine is not the same as yours. Mine's a one-off of a BM048
    [Link to post with write up of bushing replacement and part numbers etc.]

    There's a bush at the top which I replaced with a spherical bearing. After 1100km it still looks new.
    The bottom of mine only has a fork with a bolt through it. There's a rivet nut on it that has cracked. Perhaps as a result of the top bushing collapsing and allowing the bottom to flex.

    I had just fitted a brand new Michelin Desert Race, it is now toast as the flatspot has worn the knobs off so helped in not blowing the Tyre
    As to engine, not sure as I have no need to hit the start button yet
    I did not pull the clutch in as I had my hands full
    I am not expecting it to be an issue but will investigate in the next few days

    100-0kph in 88m and 5000-0rpm in half a second has to have had an impact somewhere. I wouldn't have had time to grab the clutch either.
    The chain would've taken up some of the violence so inspect too for damage.
    Sucks to waste a new tire like that, but if the shock had punctured it I would think you'd be in for an explosive decompression and not so certain you would've kept it on it's wheels. I would've performed one of my signature low-sider moves....

    I was contemplating one of those, but to be honest , riding it out was looking more attractive, lucky for me the plan worked, mind you there were moments of reflection as to the wisdom of my choice when you are thinking I don’t want to high side this as you continue along your skid and then a white post comes into vision and slides by

    You made the right decision and didn't end up crashing and tumbling down the tarmac, staying relatively unscathed and able to continue riding.

    A rear shock every 50k km isn't very expensive.

    Looking good Sherpa Nige! I am happy to help and I hope you use the heck out of them for many years to come.

    Have a fun trip!

    looking for comments:

    getting ready to buy the oem fork seals and wipes (dust seal).

    oem dust seal - 31427692145
    oem oil seal - 31427692147

    here in the u.s:
    dust seal - 31427692145 - $42.44 each or $84.88/set
    oil seal - 31427692147 - $32.72 each of $67.44/set

    while in germany:
    dust seal - 31427692145 - 17,47 € each or 34,95 €/set
    oil seal - 3142769214715,81 € each or 31,62 €/set

    strange to see at least double on the price for what we pay here.

    i'm leaning on buying them in germany since the bike is already there waiting for me.

    I've been using the "low-sticktion", green SKF brand with good success. You can get one dust wiper and one oil seal as a set, item number KIT45M, from https://mx-tech.com/ for $32.99 + S&H. There are cheaper ones around but these are of really good quality.

    Edit: any seal sets made for Marzocchi 45mm forks will fit

    I got extra XCO rear wheel and front XCH front wheel and I wonder if they need the ABS sensor wheel to be installed on each ?
    Thanks for your comments

    ...if you want the ABS to work then yes. Not sure how the speedometer works on the XCh.

    Speedo takes its signal from the rear wheel.

    What part of the rear wheel? Perhaps u haven't looked close enough but I only see the ABS sensor back there. Do the non-ABS models have this rear sensor and ring too?

    You make it sound like I do them deliberately :lol3

    Are those dealer prices or the prices off of the fiches? I generally don't buy stuff like that from BMW. I paid NOK302 (USD36) for two bearings and a dust seal for my front wheel yesterday at the SKF distributer here. Just look up the correct sizes and go to your nearest distributor.

    AFAIK all the 650's are the same here and the ABS signal doubles as the speedo signal.

    I have a bike from before they offered ABS on the 650s and even it had ABS rings both front and rear. I removed the front ring pretty quickly, and the rear ring a few years ago, but it wasn't until earlier this year that I removed the rear sensor. Doesn't look like the bike has noticed (I've not ran the stock instruments since 2003)

    Joel, since you're in SoCal make a run out to Zip-Ty Racing. They are (were) the Marzocchi importer. IIRC, the last time I did a fork rebuild for an f800 (same parts) the total parts bill for bushings and seals was less than than the bmw cost of seals for one fork.

    What if I ride my XCO with 17/21 without ABS rings at all ?
    Thanks

    If it has ABS, the ECU will probably throw a few codes (and the ABS won't work). The later ECU on the G series might react differently, but on the Dakar nothing happened (aside from the speedo not working probably).

    I've ran my X Ch (w/ABS) with no sensors front and back while troubleshooting speedo issues. Runs perfectly fine without sensors but no speedo or odometer. Currently have an issue in my rear sensor somewhere along the wiring path to the ECU. Sometimes speedo works but then stops. I use my GPS for speedo/odo now so I haven't really tried getting to the cause.
