    Thinking Of Returning To a K100RS

    I know most BMW riders interested in an older BMW gravitate to Airheads. Has there been any renewed interest for the original K's? I've always admired the original K100RS and regret selling both my 1987 and 1991 years ago. (The K1100's, while perhaps better, don't do anything for me.) I figured if any group would know the trends it'd be here.

    Thumbs up Two thumbs up on your idea from me

    There are a lot of us who have had airheads (and still do) but have gravitated back to early Ks. I bought a K100RS the first year they came out and loved it (despite a terrible stock seat and a fair amount of vibration).

    I now ride a very smooth K75S and will probably never part with it.

    I wouldn't mind having another 1985 K100RS though; they all came with the hotter European cam and additional horsepower. What a blast to ride, especially at 112 to 120 mph (sweet spots).

    Go for it!

    Cool Great Deals

    Some of the best deals for great bikes are the early K100s. For around $3,000. or so, you can get great low mileage K-bike. I like the K100RT tho.

    I bet that's because the RTs all came with a built-in heating system that can keep you warm in wintertime Detroit.

    LOL yeah I remember how warm those K bikes were. Heck the tank itself even got hot from the heated fuel. Perfect for this time of year
    Actually I wouldn't rule out a nice K75S either. I guess my order of preference would be 1) 1990-1991 K100RS 16v. 2) K100RS 8v. later the better. 3) K75S. Looking for the right one will give me something to do this winter. Meanwhile I'll occasionally lurk here to keep abreast of various issues and fixes.

    We have 4 K75s. One "S", one "RTP", and two "Standard" (low seat.

    Not the highest tech, and not the fastest, or the quickest, but still the best bike BMW ever built in my opinion.

    I am another one who had a K75 back in 1986 (a K75C) and had to sell it. Recently bought a 1993 K75S since the S model was the one I really wanted back then. There is just something about those bikes. I liked them then and I like them now.

    I, being of superior mind, realized the greatness of the early K's and never let mine go. (actually I'm just cheap)

    I had a K75 standard that was a great bike. I had a K1100LT that was very very hot in the summer months. I also have returned to the Airheads, although I do have a new G650GS just for fun...

    Cool Good heat!

    I cured the heat problem enough with after-market panels that better held the heat around the engine, so the heat never botherd me. in the winter, I would remove those panels along with the panels between the faring and gas tank to expose the motor. It was like heaven, heated seat, heated handlebars, and nice warm air blowing on my legs. I ride year around in Michigan, as long as there is no slippery roads. That 85 K100RT had well over 100,000 miles without any major problems, never let me down. Probably did around a million second gear wheelies too 100,000 miles is only broke in, I love checking odometers at rallies, Ive seen K's with 350,000+ miles on them.

    Paul, or anyone. Regarding K100's my understanding is there wasn't very much in the way of changes between a 1985 and 1990, except for ABS becoming available in what 1989? What about K75's? Are they about the same from 1986-1995 excepting for the ABS availability? Were there any meaningful improvements affecting durability or servicing that you're aware of?

    The earlier Ks have the aluminum colored cases, peg mounts, and swingarm which I like the look of. The later Ks have the blacked out cases, peg mounts and swing arm.

    Not to hijack the thread, but this is important:

    So 04gt4me, do you remember what company made these panels, if they are still in business, and where you got them? I love my '85 K100RT, but it's pretty hot in the middle of the summer.

    Thanks,
    Johnny

    Renewed interest in the K-bike(s)

    After decades riding airheads, I bought a K100RS. I'll be the first to admit I was unsure whether I'd made the right move, but after some rides and wrenching I have come to hold it in very high esteem. I'd always liked the look, but the test ride I took in the 80's put me off. The bike seemed heavy and it buzzed a lot.
    Fast forward to the present. My K100RS, in a sharp state of tune is pretty smooth. It's handling reflects a giant leap over the old airheads. The bike just loves high speed travel. I've slipped insulated jackets over the fuel lines and reduced substantially the tendency of the fuel tank to grow hot. As for riding in hot weather - and believe me, where I live it is hot in the summer - I've found that I simply need to pull my legs out from the sides of the tank and into the airstream a bit and the heat is tolerable.
    In short, my bike is a keeper; we've bonded!
