    OK, thanks for the reply on the brakes, makes sense.

    Sounds like the bikes you and I bought have somewhat off-setting issues. Although mine has the rear main seal leak, etc., the fairing subframe is in perfect condition - I assume due to the bike never being dropped. I'll have to address the worn FD splines and mating driveshaft splines at some point, but I expect they'll be good for at least a year or two with my planned usage. I primarily bought this for use as a very economical commuter (116 miles roundtrip) which will keep miles off of my GS. That RT fairing and the engine/radiator heat behind it will be welcome for at least three of the four seasons.

    I love your bike's blue color, and that Reynolds luggage rack/backrest is a top quality item. Too bad they're out of business.

    If you do want to go that route, one of the pieces on my bike has the paint code and I'd be happy to share it with you but I think google could probably do my job for me. It's a fantastic blue! I want to restore her to her previous glory. The K75 motor is not one we should let go of. Huge history in BMW's story and a motor that's just fun to ride and a real workhorse. worth preserving.

    Thanks for the paint code offer, but the metallic graphite of mine is my second favorite OEM color for that bike so Iā€™m good.

    I agree these are great bikes. 72k miles on my K75S when I sold it, and the only issue that entire time was the cooling fan motor seizing at 65k miles or so. The fan probably wore out by running so much when I used to commute on the bike in Texas.

    My old K75RT was this same graphite color, great color. Mine did not have ABS thankfully. While the RT was too cramped for my long legs, I absolutely LOVED the 3 cylinder engine. I miss that bike.

    Same here, I'd prefer no ABS and no RT fairing but here we are. I'm 6'3" I flat foot my GSA and I love the K75. going to do everything I can to keep it.

    I never had any mechanical issues with that bike, save for one pesky and stressful gremlin. For several years it would randomly lose almost all power. It happened during rush hour on I-90 on a bridge with nowhere to go, thought I would die. It left me stranded in the middle of nowhere several times. Often it would spring back to life for a while. Nothing made sense, spark plugs and wires were good, emptied gas tank, changed fuel filter, air filter, etc.

    Eventually, I finally figured it out. The computer harness was not seated/locked in properly. So occasionally just the right bump or vibration would cause it to loosen just slightly enough to interrupt the circuits enough to reduce power but usually not enough to completely shut down. Strangest thing, but an easy life changing fix. No more random strandings or close calls with the grill of an 18 wheeler bearing down on me from behind.

    Had the same problem as above with my K1100. It did it a couple of times so I ended up zip tying the harness to the box and it's never done it again.

    @AdamChandler, because you have a LC GSA for a direct comparison, how do you find the clutch lever effort on your K75 compared to the GSA?

    When I bought my K75RT in December, the clutch lever pull was far heavier than on either my '14 GS-LC or my DR650. After installing a new OEM clutch cable on the DR last year, I consider both of those bikes to have very light lever pulls (one or two fingers used when off-road on either). Upon tearing down the K75, I found it's removed clutch cable very stiff (likely the original one, 25 years and 78k miles old) and the clutch release pivot linkage on the rear of the gearbox to be very notchy and stiff also. I installed a new Featherlite clutch cable from Motobins (extremely smooth/light effort when uninstalled), and removed/cleaned/lubed the clutch release pivot linkage on the gearbox. I had the clutch out while replacing the rear main seal, and know that it was reinstalled correctly.

    After adjusting the clutch cable and lever per the manual, I'd estimate the lever effort to still be 2 to 3 times that of the GS & DR. While better than what it was when I bought the bike, the lever effort is still heavy. It's been over 20 years since I sold my K75S, and it was likely just like this RT's lever effort, but I can't remember.

    Because of on again/off again tendonitis in my left forearm that has been plaguing me for several years, if that amount of clutch lever effort is normal for the K75 I probably won't be able to ride it as I planned. Even the old clutch cable on the DR triggered the tendonitis last year.

    Good morning!

    Clutch pull on the K75 is significantly harder than my GS...and I am still using the stock clutch cable. I may swap it as you have but I agree. it's a really hard pull and then just keeping the clutch engaged (like at a long stop light), I actually felt compelled to put it into Neutral which is something I rarely do I always like the 1st gear to stay engaged in case I have to move quickly but at a long light, it was too hard to hold.

    My K75C and K75S had fairly hard clutch pulls. Cables do help, but they will still be harder than a modern hydraulic clutch.

    My R1100RS and R1100GS had significantly easier clutch pulls.

    Thanks for the confirmations. I might be putting a very clean and thoroughly serviced K75RT up for sale soon. It's been a fun winter project though.

    Beautiful K75!! Hmm,..the cable clutch pull on my 94 R1100RS has never been an issue. But, exact setup to the factory specs makes a big difference. Right down to the little nylon sleeve that fits around the barrel cable end and the cable end that maintains direct straight pull at the cable without any cable bend. Barrel adjuster has the right distance out of the mount, and the lever arm has to be at the right position at the tranny, before finalizing the cable free play. The original cable on my RS lasted well over 150,000 miles. The second cable, because I didn't set it up right and lube the ends properly, only lasted 20,000. Since then, all good.

    I also owned a '94 R1100RS, and like on every other bike I owned before my forearm tendonitis developed several years ago the RS's clutch lever effort was something I never even thought about. The clutch pull on an early '90s 1200 Sportster I kept for a year for a neighbor was another matter, but I digress. I realize now though that clutch effort has to be a determining factor for any bike I consider buying.

    Adam, it's nice to see that she is getting done right. (For those who don't know, I am the one who sold Felicity to him.) K75's really are such nice bikes.

    Don't forget that I have a complete spare front fairing tucked into the corner of my garage attic. No rush at all, it's not in the way. Shipping would be obscene due to it's size.

    Sadly no GS now, my only BMW is my ā€˜67 R60/2 (which I am smitten with!). I tried a different street bike direction to see what the fuss was all about. I now have the three below which together cost less than a new GSA. But there will most likely be another GS in my garage someday.

    Holy crap, I honestly completely forgot about the spare fairing! You honestly might have to sell it on MotoBrick or CL. I don't have the space for it and probably won't need it now that this is getting buttoned up as is. I'm so sorry I left you hanging on that. feel free to PM / Email.

    No worries at all, I can list it on either FB, CL or here if I need to get it out of there

    The tech day cares not what you ride. Lots of people on non-BMWs come for the show!
