    What bike is this?

    Hoping for some help identifying this beautiful motorcycle. I fell in love with this bike in Great Falls last summer. Can anyone tell me the year and model of this bike? Thanks for your help!

    PS. I donít post much so I hope I did this right. See attached photo.

    What bike is this?

    Looks like a K100RS, I do t see ABS , so maybe a late Ď80ís model? They only made the K100 from Ď83-Ď92. The RD was the Sport Touring model

    It is a 1985 K100RS.

    The shape of the rear corner of the seat indicates a 1985 or earlier. I don’t belive they imported the RS until the 1985 model year.

    That sure is a nice clean bike. Wasn't 84 the first year they imported the K100's to the US.

    It is an '85 model that has had the wheels, footpeg bracket and crank cover painted black. All those parts originally came in as cast aluminum color. I don't think that is the original red color either. The red back then was Lava Red that faded into a disgusting metallic orange! DAMHIK

    I must be losing it, I just realize I have the same bike sitting waiting to get cut up for parts. 51797 is right it's cast aluminum and the red is faded. I will try to post a picture later.

    The first 19 K100RSs built for the US were built between 3/84 and 5/84. These were most likely Press bikes and show/dealer demo type bikes. The next 500 bikes for the US were built 7/84 and would have been designated 1985 models as BMW starts their new year model production at the end of summer vacation.

    The same thing happened with the US introduction of the K75S. I have two of the first US K75Ss (#5 and #81) both were built in May of 1986, but were designated as 1987 models. Since new models (of both cars and bikes) usually come out in September, if they had designated them Ď86 models, the public would have, by May, thought they were already old. But by designating them as 1987 models, the public felt that this newly introduced model was truly something new.

    That bike actually belongs to and was built by one of the members of our local club BMW NorCal. ( bmwnorcal.org )
    VERY nice bike!

    I am always amazed at the amount of knowledge that exists in the MOA and on this forum. Thanks everyone for all your comments. Now that Iím really interested in acquiring one can anyone discuss reliability and parts availability for an 80s vintage K100. I donít know much about them other than that Jack Riepe thinks the sun rises and sets on K bikes.

    Quite so Frank.
    This is a beautiful bike! It looks like an later '85 as it has the second iteration of the footpeg mounts with the isolatic dampers like they used on the exhaust mounts. The earliest had a direct bolt to the frame type that had quite a buzz. Jim Miller, an old motojournalist, was one of the writers that got to ride one of the first 6 K100RS's that BMW sent to Cali as a press junket,with a mechanic in tow. They all complained about the beehive in the pegs and bars.
    This bike also has an aftermarket seat, probably a Corbin, as the pillion handles have been deleted.

    Lee, when did the BMW introduce the painted and turned wheels on the K bikes?

    The owner probably did that or had it done.

    These wheels are what I was referring to. I just ran into a set to put on my next RS project. After seeing this one now I have to polish mine!
