Another question about the front forks: Are the Showas used on the later years qualitatively different from the Fichtel and Sachs used on earlier years? Are either known to be problematic or preferable?
I believe the consensus is that the Showa forks are an improvement. My K75s have been 1986, 1988, 1994 and 1995 and the only forks I took issue with were the cushy long travel forks on the '86. I converted them to K75S fork internal parts in 1988.

There seem to have been a lot of different forks available on a K75 depending on year and model. I presently have a 1992 K75S which was very early production and does not have the Showa forks that '92s are supposed to have, but rather have the sport "S" stamped on the top of each fork. Then I have a 1990 K75 which a VIN check says is a "C" model but came to me with a rear disk, Pichler Uni-4 fairing, low seat, high bars, and BMW belly pan with crash bars (a strange bike). The forks also have the "S" stamp on the top, which I understand means "sport", but is there some other meaning that can have?
Bonus point followup question. How do the Sport forks compare to the Showa forks?
I had been under the impression Showa forks were first used in the 1993 model year?
That IS a strange bike!! What exactly is the “Pichler Uni-4 Fairing”? Is that just the standard “C” bikini fairing, or something else? And I have seen belly pans on some “C” bikes as well as “Standards”, but never with any rhyme or reason - - have often wondered about that. Crash bars are nice!

The Pichler Uni-4 is one of several fairings made by Pichler of Germany years ago for a variety of bike brands. The Uni-4 is a frame mounted half-faring styled somewhat like the classic Windjammer. It has two storage compartments with locks, and spaces for an optional radio and speakers. You very seldom find them any more. The picture below is not my bike but shows the Uni-4.
Gotcha on the belly pan / crash bars. I see what you mean.
The Pichler Uni-4 fairing is nice! So your VIN says “C” - - I guess the original owner must have ditched the bikini fairing? Plus you had rear disc brakes. A strange bike for sure. It almost seems like there was yet one more undesignated model of the K75 for a year or two. Maybe these should be called the K75NS (“Non-Standard”)!
Another question I had concerned the later bikes with upgraded 55A alternators. Was this considered a desirable improvement? Any known issues or concerns as a result of that change?
Great feedback on the alternator. Thanks to both of you.
I definitely share the “more is better” mindset, so the 55a version seems like a good way to go. Just wanted to understand whether this “upgrade” came with any sort of downside. Doesn’t sound like it.

Just get the later K75-K100-K1100 alternator with the correct cup already on it. Don't waste your time trying to adapt an R model alternator.
Well, you’re getting a bit ahead of me now. I don’t even own a K75 yet!
