OK, so I'm the muppet who bought the wrong seat for my early 8V RS. Wrong Seat 61740 The seat on it has completely gone, the cover is non existent and I have used an old leather jacket to try and cover it, the base is corroded beyond repair. So, I found a lovely one on eBay, I skipped to the shed with new seat ready for a quick half an hours work, attached it all, went to bring it down and it wouldn't go! Turns out I have bought the wrong one, the one I need has a flat (ish) base and this one has a lump in it!!!  

So, I can see they have the one I need in motorworks but they still have the metal base, is there any other that would fit with a plastic base as this seems to be a big problem.

Hope that makes sense!

Also, if anyone needs a seat in tan leather I have one!!! Wrong Seat 259495 

Thanks in advance 

Dave

Show the underside in a photo.

Early 8v has a steel base and handles in the seat,

Later one is plastic base and no handles.....they are in the ducktail. You would need ducktail and seat fittings.

K1100 one is also plastic base has a big lump goes down between frame tubes. But won't fit early ducktail. You would need ducktail and seat fittings.

But...what if you remove the cover of the underseat tool tray.......will it then close????

You must have a later comfort seat with the bulge under the pan for more front seat padding.  You can remove the tool tray for clearance, but I think that requires a different housing for the ECU.  Possibly just remove the tray lid.

Here is some of Duck's "Seat-a-palooza" offerings.

http://www.bmwkbike.dx.am/CLseats/kbikeseats.htm

Shows the pre-1986 has the incorporated handles as part of the seat pan, metal or plastic seat pan does not matter. The pre-86 Corbin seat does not have the incorporated handles. The pan is extended in that area.

Offerings currently on the interwebs across the pond

You need a low seat brain(L-Jetronic/ECU) holder if the seat pan sticks down into the frame.

It might just be a matter of hinges adapted to the seat base. Because on the bike frame, the hinge holding points are the same whatever the bike year/seat design.

I did it the other way through: I have a k1100 which had a so called comfort seat. That seat had a plastic base.

As that comfort seat is not comfortable at all in case of long legs, I looked for a better design and found it in Motorworks here, Ref SEA50646

That one, which permits to be sitted 7cm further back has a steel base. The thing to do to adapt it on my k1100 was just to fit the hinges corresponding to that type of base. So I assume that it also works in the other direction.

Contact Motorworks, they know their business and will probably wish to keep their reputation when guiding you, even if you purchased your seat elsewhere and are just candidate to the purchase of hinges...

My 92 K100LT has a Comfort seat and it very much lives up to its name. It does not have the projection underneath so still has the tool tray. For me, 5' 8" I found it quite high but extremely comfortable. The K1100 seat is considerably lower and much more manageable.
