    K100 or K75 seat identification

    I got this seat as a extra part, with a 1986 K100RT I purchased. The guy told me it was a "low" seat for the K100 and K75 bikes. The pn on the seat is 52531308113, but I can not find this pn on either K100RT or K75 RT BMW parts fiche. I hate to throw it away so Id like to identify what it is so I can sell it cheap or give it away. I no longer have the bike. Any ideas?

    The number on the pan is not a part number.
    Looks like it could be a low seat.

    I am almost certain that is the low seat found on K75s set up for the low seat.

    I may be interested

    I may be purchasing a 1987 K75S this weekend. I am 6' 1" and the standard seat felt a little tall for me. I like my feet flat on the ground. Can I let you know this weeks end?

    My understanding is that the seat swap is more involved than just replacing the cushioned bench.

    There is a K75 here on my local market that had the low seat swapped for a standard seat. (Unfortunately, I need a low seat.) The owner told me he spent something like $600+ making the conversion to the taller seat. (It wasnít clear to me whether those were DIY costs, or he payed someone else to do it.)

    There are significant differences. A low seat is best used as a replacement for a damaged or worn low seat and a tall seat is best as a replacement for a tall seat.

    The tall seat is hinged at the side and has a release pin at the lock on the opposite side. The lock mechanism pushes in. The low seat does not have a hinge. It has recesses into which two small hook like pins slide at the rear of the seat. It has a latching mechanism at the front of the seat. The lock and latch mechanism has a lever that rotates.
