    Why is the 85 K100 the "Finest Year K?"

    I've seen the 85 K100 refered to as the "FYK" or Finest year K. Is it really that good? Why?

    That's pretty funny. The 1985 K100s, were, in a lot of ways, their own bike. They have a different seat and tail cone combo along with some other differences, one of which is different cams. I think..

    Anyway, Don Eilenberger had one and dubbed it the FYK quite a long time ago. Looks like the name stuck.

    Some bikes. Some with motors, some without.

    Absolutly its the finest year. I got one.
    Seriously the '85 K-model is probably the simplest to work on, no ABS, 2-valve engine, lightest?, at that time its dependability was unknown,as now we know its good for 200,000mi.
    All I know for sure is, if you keep it well maintained it will give you good dependable service for a very long time, unlike a certain Triumph that I know of.

    Dave is absolutely correct. The story is kinda funny.

    I was asked to give a K-tech session at the RA National Rally in Greenfield MA some years ago. (Dave was Chair of that rally..)

    At the time, I owned an '85 K100RT, and was somewhat defensive about the scorn heaped upon the '85's by owners of later K's.

    During the tech session, several people made somewhat disparaging remarks about the '85 K.. and finally in response to one of the remarks I sarcastically said "Oh - you mean the FINEST YEAR K?"

    It got rather a large laugh and I thought that would be the end of it.. but I started referring to my K as the FYK100RT in messages to the IBMWR mailing list.

    The name stuck. I started seeing it used in ad's for '85 K bikes, it started appearing in people's SIGs on messages, and questions like this started popping up - "Why is the '85 the Finest Year K?" I've even seen it used in articles in a certain national club magazine

    As Paul Harvey would say - now you know the rest of the story..

    Oh - the '85 K100's had one advantage over later K100's (until the 4V engine) - they were the "fastest" ones. They had a euro intake cam (except in California) that gave a real 90HP. Starting in '86 all K100's received the California intake cam that gave about 5 less HP - but BMW never changed the specifications.

    There were some features that BMW did improve with later K100's - heat management was generally better (but still awful on an RT) and buzz/vibration was reduced a bit... but the '85 bikes were a real bargain since you could usually find one for $1,000 or more cheaper than the same bike as an '86. This changed as the FYK rumor spread

    1985 Srtong bike

    The 85 K100RT I had was indeed ÔÇ£the finest yearÔÇØ. Aside from the dreaded ÔÇ£buzzÔÇØ the motor gave you on the highway, the bike was reliable as a hammer. I later sold it to upgrade to a 93 K1100LT but the motor on the 85 seemed to be tighter than the 1100.

    I have to admit I like the 1100 better overall.

    Absolutly, the white ones were faster because you got there faster, due to every body in front of you probably thought you were a cop tailing them and pulled over to get out of your way.Am i for real...matthew

    Ha! I've enjoyed reading all the responses to my original question. I've seen the '85 called the FYK by at least 4 different people in as many different places, and now I know the rest of the story!

    My friend Tim Balough had a silver '85 K100RS. He and his wife Linda ("Last Year" R100CS) and I ('81 R100RS) rode from Indianapolis to the 1986 'MOA at Laguna Seca together and I was very impressed with how his K made torque in any gear. I challenged him to do the slow hill climb into Laguna Seca in 5th gear and he did it with ease.
    He did have instrument cluster problems, which I understand were quite common with the early K, and his fuel gauge quit working somewhere in the Pacific Time Zone.
    He was leading as we rode through Utah and kept passing gas stations at a point where Linda and I were pretty sure he needed fuel.
    Finally, Linda hailed him on the helmet-to-helmet communicator, "When do you plan to run out of gas?"
    "Right about here," he replied as his engine quit and he coasted to the berm.
    Linda emptied a plastic saline solution bottle she carried for contact lenses and they used it to transfer enough gas from her bike to his to get to the next gas station.
    Here's the proof:

    Hi Don,

    You don't happen to remember the part number for the Euro cams? I have an '84 head that has the same cams as my '88 head...thought I was getting the euro cams with the earlier head.

    Hi Greg,

    Sorry, no - dunno the PN.. but have you played with www.realoem.com - perhaps spec'ing an '85 euro model for the lookup?

    A high percentage of the '85s imported had the California cams. The easiest way to ID them-assuming you could find an unmolested example-would be to check the emmisions label under the seat; if it has the hotter cams, it will say 49-States on it.

    It is probably possible to ID them via a code on the cams. I don't recall them having part numbers on them.

    Correct; but a better way is to hop on it and twist the throttle at 4,000 RPM in any gear. You will know it for sure.
