Thread: 1990 K75s rear wheel cap/cover/hub cap?

    1990 K75s rear wheel cap/cover/hub cap?

    I am trying to determine if I am missing a cover for the rear wheel (covering the lug nut area) Looked at a million pictures and videos, and can't really see one. Usually covered by the muffler and bags.. I do have a black cap or plug in the center hole, but nothing covering the lug nut area. Black/silver Y or snowflake rims. My old K100 had a silver cover that had clips to fit into the center hole which covered the lug nut area. Mu 91 K75C had a silver slotted cover, 3 spoke rims. Did the 1990 K75s have a cover? If so what does it look like?

    TIA

    Well, my father's 91 RT and my 95 S both have a cap that covers the whole lug nut opening area. My dad has the black "snowflake" rims which uses a shallow "dish" and I had the silver "Y" rims which used a flat cover that fit over the area that sat flush with the rims. Oddly i have no picture to help you out with.

    The parts fiche kind of shows it:

    And BeemerBoneYard has better photos

    The wheels that you are calling "snowflake" are actually called Y spoke ( if you look at the spokes, you will see 4 "Y"s with the bottom leg of each Y connecting to the hub and the two arms of each Y connecting to the rim). Airheads had snowflake wheels which are different.

    The wheels that you are calling "Y" spoke are actually called 3 spoke.

    BMW made 3 different hub covers for the K75 in addition to the small center hole plug. As far as I am aware, all K75Ss came from the factory with one of the full hub covers.

    The '87 Ss came with the silver dished hub cover to match their silver Y spoke wheels.

    The '88-90 Ss came with the black dished cover to match their black Y spoke wheels.

    All later Ss came with the smooth silver covers to match their silver 3 spoke wheels.

    I have looked at several microfiche's, trouble is (to me anyway) they don't identify the year. In the MAX BMW fiche, the diagrams are #36, 0164 and 1535. Both are the 'Y" wheels like I have, Fiche number 0164 shows the center plug like I have (#10) and also shows what looks like the cap in question (#5) in fiche number 1535 it shows the center cap or plug like I have (#2) and does not show the larger cover. I think this is the drum brake wheel model however. Neither fiche is broken down by year that I can see. On both my old K100 and the K75C the center cap was held by a clip that fit into the center hole. With the black plug in (like I have) the center attachment would not work.

    Neither cap for the silver Y spoke or the black Y spoke wheel are available anymore from BMW.

    The plug is not used when using the hub cover.

    K75s and K100s with Y spoke wheels used the same covers. The black ones are less common on the used market due to the high use of the silver Y spokes on the standards and RTs. You could always buy a used silver one and paint it black.


    Call one of the recyclers in the Owners News.

    I only saw 2 silver ones on eBay; a broken one for $30 and a good one for $50 plus shipping.

    I actually found one overseas for sale, what confused me is that center plug. I can't see how it could be there and the cap fit. Seems funny that they would have both. Learning more about these, even though I have had a few of them..

    The "cap" will NOT fit with the center plug installed. The cap has two metal fingers which insert in to the center hole in the hub and hold the cap in place with spring tension.
