    Who has an R100CS still on the road?

    I own 2 1981 R100CS's that are in good to excellent condition. Neither has original paint, but both have been repainted in "legal" paint schemes for the year and model. My serial numbers are 6188073 and 6188103. I would like to know of the existence of other R100CS's (USA only - S/N 6188001 thru 6188174) still on the road. Note that S/N 6188001 thru 6188163 are 1981 models whereas S/N 6188164 thru 6188174 are the only other USA delivered R100CS's with the 0436 motor, and are 1982 thru 1984 models, and are truly RARE. Last Edition R100CS's delivered in 1984 are, in reality, R100T's with 0435 motors and special pearl white paint, and do not have "R100CS" stamped on their frames.

    Thanks,

    Well my Buddy John still occassionally shows up at rallies on his CS. He rode it to the 49'er rally last year. I guess technically it won't be to last years rally until tomorrow. He also rode it to the Top of the Rockies rally. Going over some of the passes in Colorado it was definately suffering from the elevation. Not a whole lot of passing power.

    I believe his is an '81. I don't know the serial #.



    He had thought about trying to sell the CS at the 49'er rally because this Motosport followed him home. He changed his mind and they are both happily living in his garage now.

    I'm not sure if mine qualifies. It's a 1982 model that I was told was a CS. However the side covers only said R100. The first owner replaced the S fairing with a Luftmeister and put wider bars on it, so I never saw it as orriginal. I found a 1982 BMW sales brochure that shows no S or CS models, but lists everything as an R100, but shows both with and without the S fairing. I bought it with 13,000 on the ODO. It now has over 100,000. I'll be riding it today in our annual New Years Ride.

    I know of 2 personally; one in Mass & the other in Va. I painted the one in Mass several years ago & it has been given a museum quality restoration. I believe the one in Va. is totally original & still in very nice shape. Both are early "true" CS models.

    Cs?

    What does CS stand for and how are the bikes different from an S? Inquiring minds want to know.

    I have heard that CS denotes "Classis Sport" as after '79 or '80 there was no R100S????

    Rod, I did a little research in my BMW motorcycle library, such as it is. I have two of Ian Falloons books on BMW twins, which give a fair amount of info on CS's. Kinda confusing, they show R100 emblems on CS's like U pointed out. The title of his two books are "BMW Boxer Twins" and "Original BMW 50-96" The Restorers Guide. Good text and pictures. Also his book BMW R90S has more info on CS's. also good text and pictures. Cycle World ON BMW 81-86 also has a good article on the CS. How was the ride? See U at the spring meeting.

    Hi Dave,
    Nice to see your bike again. How many miles now on your original one?
    My other bike is a BMW.

    Curious how you believe there are differences in R100 motors post 1980.

    Don't get too many stars in your eyes around the term "rare." It's just for eBay.

    No 1984 bike has its model name stamped on the frame, BTW.

    IKCHRIS,

    Have owned 6188073 since new, and have no stars in these eyes. However, it is fun to discuss just because of all the bikes out there that are purported to be R100CS's and are in fact NOT. Maybe for EBAY for you, but better to keep everyone straight. Worldwide production was 4038 for these but only 174 were ever delivered here. They are, therefore, relatively rare here, and can therefore command a higher price. This is simple economics.

    The Chief Joseph ralley in early June is a awesome event.
    Then again who's to say that a hand full of riders can't just pick a weekend and go camping?
    I will continue this thought in a couple of months.

    Thanks Bob
    I am looking forward to meeting with like minded souls
    btw
    my bro in law has a beauty, original, pearl white cs
    it was recently appraised at BMWNW (Eugene) at 9.5k
    yet , as strange as it might sound, I like the ride of an rt better for wind buffeting, rider comfort, etc
    but his is a beauty, wiht matching white hard case side bags ( yes white, never seen it before his)
    maybe I can drag him ( force him to take a day away from his job)along for the rally
    ahhhh....an Oregon rally , in the honor of "tim the tool man"...r.r.r.r.r
    dont know how else to write it
    out of here
