    I think so.

    I don't know. I've seen some different saddles on various K bikes and not all of them were aftermarket. A friend with a K1100LT told me that it had the same saddle as my K75RT (or at lreast interchangable.)

    The only one I know won't exchange is the '85 K100 with other years.

    But this opinion is worth no more than what you paid for it.

    The '91 seat will fit a '93. HOWEVER, I think the '93 and '94 K seats were among the most comfortable standard seats ever made for the original K series bikes, and were much better than the earlier ones. The foam seems a lot more robust and the covers last a bit longer.

    I might be completely losing it on this one, but I've been stockpiling spare seats to make sure I will always have one.

    What about the '95 seat? I'm certainly happy with the comfort level, but then again, I have a Brooks B-17 on my road bicycle and most would consider that an instrument of torture.

    The seat on my '95 has seams on it, unlike most of the ones I see in pictures which appear to have a seamless covering. Also the cover looks like leather. If I look at the underside where it is stapled to the pan, I cannot see fabric backing that is typical on vinyl. Instead it looks like the back side of a piece of leather. At one point I thought it might bave been an aftermarket seat, but the pan has the BMW logo on it and my understanding is that the early Corbin seats were built on the OEM seat pan, not the later ones. I also recall hearing that Corbin made some seats for BMW but have not been able to confirm that.

    If its got seams, I think its the Comfort Seat. I've never tried one.

    You're more than welcome to try mine the next time we meet. In fact, I'd be delighted to have you ride my bike and let me know if everything feels like it should.

    Sure, bring your bike over. Can you mow my lawn while I'm out riding? You know, since you don't have to do it at your house?

    Hi Hank,

    I can tell you for sure that Corbin did make seats on the stock BMW pan - I had one. Mine wasn't leather although that was offered. But if yours is a Corbin, seems like you would find a logo somewhere.

    Welllll... if it's at all like the K Comfort seat from that era - you can buy them brand new for a reasonable price (about $245 from Hammersley). I got one a few months ago. No seams in the seating area (I've seen other Comfort seats that had sewn cushion pattern in the seating areas).

    Mine had a manufacturing date of 2003 on it - so they're still turning some out. Came direct from Germany to me via Hammersley. Had it in a week. Also worth checking the price at Chicago BMW(Harley)..

    Oh - the neat thing on a comfort seat- it's (surprise!) COMFORTABLE. A first from BMW in my experience.

    Haven't talked to anyone who had an insert in the seat, but I know some of the aftermarket seat manufacturers stopped offering them.

    I have heard they're cold in the winter and hot in the summer. I have one that straps on the seat - can't say it did any good (and I have bad hips - so if it did any good at all..)

    I have a '94 K11LT that came with a Comfort Seat, and it was a good one. I rode many long days with that seat, but eventually replaced it with an aftermarket unit.

    As for gel inserts, I have one in a seat on a Moto Guzzi. It is terrific. the secret, I think, is to install the gel pad under a layer of foam so that your butt is a bit isolated from either heat or cold.

    The only downside for me with the gel seat is that it adds height (which I REALLY don't need).

    Comfort seat

    I rode160,000 miles on a stock '91 K100RS seat and never felt the need to tinker with or replace it. I decided a long time ago that what you wear has more to do with comfort/discomfort than the seat design. I've worn spandex bicycle shorts under my riding pants for years. That and a couple of mid-afternoon aspirins will get me through an 800-mile day.
    That said, my '03 K1200GT came with a Comfort seat and I love it.
