    Rear Shock...need adjusted or worn out?

    I have a 1999 R100GS and I noticed the other day that when I am riding two-up the bike will sometimes "bottom out". I read where there is an adjustment; however, I have turned the knob to harder (stiffer or whatever) and have been unable to get the little black screw on the bottom of the
    shock to move in either direction. The bike has 39,000 miles. What say you?

    replace it. it's cooked.
    the small screwdriver slotted adjuster is for rebound damping- (clockwise turning slows down the extension of the shock after a compression). the large side knob handles preload. that is the one that you really are concerned with- but stock shocks are really only adequate for about 25-35K miles. get a rebuildable unit (do a search on the subject- its a common question as to which one to get).

    Rear shock

    So can anyone tell me what brands/ types/ manufacturers are known to be reliable with good quality for this bike? I knew from previous bikes that I would have to replace the shock soon I could just use a little guidance please. Thank you all.

    Tons of info on this if you do a search. I spent the $$$$ to put Wilbers on my 94 RS and am STILL impressed by the ride quality and performance 40K after I installed them. They aint cheap, but worth every penny.

This keyboard does not care what I type or how valid my opinions are.....

    I just wanted to hear what people, as of today, are saying. I would imagine you could have given me your honest opinion on the subject in the time it took to twice point out your brilliant idea of doing a search on the subject. I do appreciate the fact that you gave me the advice of doing a search; however, if I want to be treated like I am annoying people I could have stayed on the FJR forum where their idea of posting is to rag on each other.... Has this forum changed to something I am unfamiliar with in the several months that I have been gone?

    Seems we have a few here that enjoy pontificating to the inferiors.

    If you restrict your search to this sight you will get opinions that are pretty accurate, as long as you are talking shocks.

    I have Ohlins and love them. About 40K on them and they are still good. Would I buy them again, sure. If another brand was $100 cheaper, probably. If another brand was $200 cheaper, nope.

    That said, it ain't rocket science, and I really doubt if anyone here could really tell the difference between Ohlins, Wilbers, Hyperpro and who ever else makes these things if properly set up in a true blind test. They are all so much better than what you have, you will wonder why you never did it sooner.

    Buy what floats your boat. Put it on, adjust the sag and damping, and then ride.

    I won't dispute the limits of the stock shocks and I won't dispute the improvement possible from replacing the stocker with one of the premium replacement options.

    However, what you have described is caused by the loss of the oil in your preload adjuster. There is a very simple procedure where you open the preload adjuster and refill it with "jack oil" which usually restores the range of setting on that knob so you can adjust your preload to high for two-up riding. This won't turn your rear OEM into a Wilburs or Ohlins but it could fix your immediate issue.

    Look here:

    If your rear shock is beyond use, you could also check with bike breakers and also guys who sell a lot of the replacement shocks; they may have some of the OEM take-offs, some with low mileage.

    I think one of the problems with forums is the same as the problems with emails. People write things they would never say to your face because it is just plain rude.
    I plead guilty to this offence many times over my +35 years of farting around on computers for work and play. It just happens.

    Lots of regulars read this forum every day and there are a lot of questions that come up repeatedly simply because we all own the same motorcycles. You know, the reason we come here! It helps to remember that. If you are reading the forum every day in hopes of fresh original problems every day, well, it's not likely to happen.

    I have not yet replaced my shocks but at 21,000 miles now I am sure thinking about it! After reading tons of threads on it like this one : http://www.bmwmoa.org/forum/showthread.php?t=26771 it seems to come down to the same four answers most (but not all) the time:
    Ohlins, Wilburs, HyperPro and Hagon. I think maybe even in that order too.
    Lately there have also been mentions of YSS and others on the forum as well.
    You can even get custom made air only shocks from a place in Ontario whose name escapes me at the moment. VERY expensive but supposedly they last a VERY long time and are simple to adjust using only air pressure.

    All kinds of solutions out there, all of them ranging from a bit more expensive than the original Showa shocks that come new on BMW bikes but worth the extra cost because you can have them rebuilt easily and save money on the long run.

    There is a shop in Ontario that actually does rebuild BMW OEM Showa shocks. It is called Brunos. Here is the link but I notice the shocks part of his new website is still in progress so call or email for details on your shocks I guess. http://www.brunos.us/index.html

    I am not going to go this route myself when the time comes since the one thing I read here about shocks that is consistent is that Ohlins, Wilburs, HyperPro and Hagon shocks are ALL way better than the original Showa shocks and worth the expense. Now that I think of it, since winter is coming on... maybe that time is NOW!

    If you can afford aftermarket, consider Ohlins or Wilber.
    Ohlins will have more rebuild shops and parts if needed.
    Wilber will be a couple of hundred cheaper.
    IF you are working on a tight budget, contact this guy, he can rebuild stock shocks:

    Don't look at the cost as spent $$ like tires, as when you sell the bike, it will be worth more, or install the OEM and sell the aftermarket and recoup on average 2/3 of the original cost.

    So take the $$, and divide by 3 to get the real cost of the purchase. Then add the better ride and handling you will enjoy in the mean time, and it is a win-win.

    Here's another after market shock question. Maybe you Ohlins and Wilburs owners know...
    I notice that when you need to get under the alternator cover to check or replace your HES or your alternator belt an Ohlins shock is too big to allow removal of the cover.
    Is this also the case with Wilburs or HyperPro or YSS or ??

    To me that is a negative on the Ohlins front shock.

    anyone who can rebuild shocks can rebuild any brand at all, as long as they have access to parts. the work & guts is pretty much the same.
