    1977 R100RS (euro)

    My friend has many bikes and I asked him to consider selling me one of his stalled refurb projects. He showed me a 1984 R100S and this 1977 R100RS. He says this bike, the 1977, is a Euro import and one of only 200 or so made by BMW. He has all the parts, had the motor tuned and cared for recently and upgraded the electrics. He also has sanded down all the body work and had planned to pain it.

    It needs re-assembly and he claims to have all the new parts for the bike and a clean title. He says it's rare and worth 12-15K when perfect. I balked but he broke the ice with a suggestion of 6k for the bike. I offered that I should get both for 6k and told him I would call him later and chat with him about the money.

    When I use the VIN decoder I get the following info:

    Chassis number 6080803
    Vehicle code 0306
    Series 2474
    Model R 100 RS
    Body type ohne
    Catalog model ECE
    Production date 1976 / 11
    Engine
    Transmission
    Steering
    Catalyzer NONE

    That doesn't mean much to me but I'm sure it is meaningful to someone. Also, when fully dressed and in great shape I don't see them going for much more than $8,000 with a more common price of about 4k.

    Is this a project worth more than I think it is? I'm interested in another project bike as the pistons are still frozen in my R100's cylinders but I'm not sure this is it.

    I appreciate your honest feedback,

    The attached image is not a 1977 R100RS

    It is a later single sided swingarm R100RS model 1992-3?

    I don't get the rarity...200 produced? In 1977 model year alone, it appears over 6500 were built for Europe with the 608xxxx VIN.

    I think they made 200 with 40mm exhaust.

    He had a 1984 R100S sitting beside it and it had the smaller exhaust. He claims the exhaust on the 1977 was 40mm.

    Also indicates that the VIN is euro spec?

    This site:

    lists VINs and separates US and non-US machines. The 608xxxx is the non-US bikes while 618xxxx would be US bikes.

    The other VIN search engine confirmed that it was made in 11/76 as well. Looks like a non US bike.

    FYI,



    I sold this US first edition 1977 RS for $7500 with 40,000 miles about 2 years ago.

    You'll notice some of the stock items that make the bike special including: pinstriped spoke rims, blue brake calipers and 40mm carbs just to name a few.

    This bike was restored in the early 90's (repainted and many parts refreshed) prior to my purchace. It came out of a private collection, just sitting collecting dust.

    It only had 22,000 miles when I bought it for $8000 in 2001. The paint job was thin and it showed some wear after I rode it pretty hard for 7-8 years and 20K miles.

    The bike looked awesome and rode wonderfully fast in a straight line. I never cared for the handling characteristics when cornering at higher speeds. I stayed away from making any modifications as not to take away from the stock set up on the bike. I bought a super low mileage and clean 1995 Mystic with the cash and it handled, rode, stopped sooo much better than the RS. It was night and day.

    Beneath the fairing, brackets and extra few wires lie a common BMW engine / transmission and drive layout with maintenance that is only slightly more complex than a box stock R75/7 which was my first new BMW motorcycle. There are lots of nice improvements made by owners of the early 77RS in the same manner that people breathed life into the R90S. I dont know what you are looking for other than a project. I dont know how familiar you are with these machines so I couldnt recommend the 77RS to you. I collect 76 84 and have a preference for 77 / 78. My ideal airhead would combine certain elements of the first year RS with the early 80s engine, clutch, brakes and electronics. I think that with the 77RS however, you would stand a better chance of having a fun BMW to ride one that turns heads as it goes by because its fast and good looking but also, because it has been a collectable BMW for some time, you are more likely to get a larger chunk of your money back if you sell it. Not any 10 or 15 grand though.
