I got Spieglers for my K75s. Excellent quality and perfect fit. Unfortunately in my case, when I got them I discovered that the PO had made some modifications and that I did not have all the stock components to attach my new to. I discovered this while complaining to Spiegler that the hoses were too short - and they graciously pointed out how they were correct and that I was missing some hard lines. If your bike is unmodified, you should be fine. I'm happy with mine, now that I acquired the missing components.

Which components were missing, Scud? My bike doesn't have a center tube feeding two separate brake hoses. Is that what you are referring to? My bike has a single hose from the handbrake to the right caliper and a pipe bridging from there to the left caliper. That is one configuration that is stock, not a modification.


Describing the array and supplying the measurements is appropriate when ordering online.

Are you sure yours is stock, Laitch? The downpipe feeding short hoses to each front caliper looks standard across a range K75 bikes (realoem.com), 1995 included.


By the way, what's the difference between K75C and K75T? There seems to be a mix of windshields and handlebar heights no matter the designation.

This is not true for my '94 K75 RT and S models w/ABS which have a hose to the right hand side caliper and a hard line crossover to the left side caliper.

When you order lines you need to be very careful to get the correct model, year and whether or not the bike has ABS.  My experience with the Spiegler lines on eBay is that they have the correct lines for the bike.   But you have to order the right ones.

According to the BMW parts fiche, John, it's one of the stock variations. Attached are two variations of the front brake layout found under K75S in the MAXBMW parts fiche. Mine is variation #2.

A C has a drum brake. The T model was a touring variation sold in the USA but the later models had disc brakes all around.

Thanks for the clarification, Laitch. - J

A bit late to respond, but...


My 1990 K75s had the pipe through the steering stem. It was a non-ABS model.
My 1992 K75s had ABS - and it had a single flexline to the RH caliper, and the solid line arcing over the wheel to the LH caliper.
FWIW - I deleted the non-working ABS from the 1992 and moved all the non-ABS components (and forks and triple-clamps) to my 1992 "keeper."


As for missing parts, Laitch, the PO of the 1990 had run new lines from the downpipe directly to the front calipers, and had eliminated the hard lines. When I got the apparently too-short lines for the 1990, I assumed Spiegler had made an error, but then I learned that I was missing parts, not them.
