Nice bike, I use to have a 88 K75s same color Marakessh Red. Very smooth inline triple. Rear spline was the Achille's heal, its pretty easy to pull it loose and apply the BMW spline lube. Eventually a BMW tech I knew, tapped a fill port and I used gear oil (no more lube every oil change) until I traded it for a K100rs....

skids that's a nice bike. Man built it and man can fix it! It looks like you got that leak resolved with a new seal. YT is a wonderful tool.

The K75 is a wonderful machine. My wife bought me a 1992 BMW K75C back in 2020 and like you it is a motorcycle that I long had my eye on. One came available locally and it made its way to my garage.
A creampuff with less than 20K miles on the clock but it had sat in a garage for almost ten years with a once or twice start annually. After buying it I had to replace tires, brake lines, clutch cable, have a clutch and spline lube done and refresh all the fluids. But once that work was done it was magic to ride. Unfortunately for me time and interest caught up with me. Time being an aging body that began to recognize the weight of the machine, and interest being a growing desire to ride off-road. So I reluctantly sold it to my way for a Himalayan. But if I were younger, that motorcycle would have been with me a long, long time. I hope you find many miles ahead on yours. Here's mine on one of my many rides through the central Pennsylvania landscape... ![]() My 1992 BMW K75C on the way up Jack's Mountain near Belleville, Pennsylvania.

I had a K100RS too that I bought from a guy that kept it in a barn. It started and ran beautifully, smooth idle but I thought it was a bit gutless, I was bit disappointed but I bought it and took it home and began going over it, oil changes, the usual. I pulled the airbox to put in the new filter I had bought and the box was a mouse condo! Packed with straw and paper and mouse pucky. When I cleaned it out, wow! That scoot came alive and now I'm happy! The fuel injection compensated for the nasty plugged air box and it ran beautifully even with that handicap. Excellent bike but it had to be moving, slow speed was not its forte.
You'll be happy with your K75. |

K100rs was a fun bike to ride, it did have a buzz zone around 5k RPMs which made it feel like an angry buzz saw, but it was definitely an autobahn cruiser. I traded it for a K1200rs which was smooth as silk

When we were back in Minneapolis, Trixie traded her 750 Ninja in for this K75 factory low-seat model.
She added a color-matched BMW R90S quarter fairing, bars, a chin piece and bar end mirrors. Later, she had the factory black wheels powder-coated an aluminum silver. She also added a Staintune slip-on muffler. We brought it with us when we moved to Rapid City in 1993, where she eventually traded it in for a new, '98 R1100R. I don't remember how many miles she put on it, but it never gave us any trouble, though they do tend to run relatively hot. It was a very comfortable bike for distance rides. Modest power, but enough for anything a sane person would want to do. ![]() ⚠️ Last edited by JBacklund on UTC; edited 2 times

I admit I was and still am a diehard BMW airhead fan. The Airheads were not fast, but the ease of maintenance, simplicity and reliability, made me fan for life. But I had a riding partner that owned a K75 and we would switch scoots when on trips together. I had a 75/7 at the time, my third BMW, and riding the K75 was a whole new experience. Heavier, so it handled differently, of course, but the fuel injection and water cooling was a benefit even though it made the machine more complicated. But what a machine! A couple of thoughts I vaguely remember - 1) Use the center stand when parked any amount of time as a wee bit of the oil will seep pass the valve seals and give you a smoky start up. 2) The fuel injection system will recirculate the gasoline back into the tank to relive the pressure on the line when riding at a slower pace. So you will notice that the tank may get a little warm if you are just doing some riding down back roads that include some small towns. Just some quirks like any other machine out there.

I had two different K75's back in the day, with a Honda 500cc Silverwing motorcycle between. All of the Kbikes are automotive in their construction and reliability. They just keep on running.
The comment about the gas tank getting a little warm was right on. Both of mine got HOT ! It was so well known it was commonly called "K bake." I almost passed out on one crossing the Chesapeake Bay bridge one August in high heat conditions , on the west bound span, the worst one, in full leathers. I pulled off at the state park off the bridge to cool off. The tank was so hot that you couldn't hold your hand against it. |

While in college, I was on the college bowling club (we received no support). The lanes on campus had Brunswick pinsetters. They were beautifully simple machines. The coach/man in charge there told me it was the worst business move Brunswick ever made. Those pinsetters, named B2, were designed and first built after WWII, and many were still functioning without major repairs in the mid 70s and today.
If you have ever looked at an AMF pinsetter from behind, it looks like a Rube Goldberg machine in comparison to the B2. But Brunswick quit making the B2 for the same reason BMW quit making K75. |
