    I bought one of these things and installed in on my 2016 GSA. The installation took about 15 seconds and is easily reversible. I have a 30 inch inseam and the regular height Seat Concepts seat. Overall it does give me a noticeable lower bike although I also noticed that the tilt towards the tank has increased. Im going to keep it -I like that for $40 I can get a bit more of my feet on the ground. I do tend to slide forward towards the tank - but not that bad. The sliding towards the tank can also be alleviated with acceleration...

    The name escapes me, but there is a UK dude that makes a similar set-up from metal. Cheaper too IIRC.

    I would take the stock rubber stops and grind off 10mm than apply some RTV (or similar) to the opposing side of the rubber bumps to take up any slop, easily reversible for about $10 by replacing with new OEM part.

    Question for you since you're the first person who has these who's posted about 'em.

    Can you use these to raise the front of the saddle a little bit as well? Their website seems to indicate that you can, but not conclusively.

    I'm interested for using them to add just a little more rearward tilt, less than you'd have if you had the front of the seat on high and the rear on low. Something just a little more up from level.

    Yes, you can raise or lower the seat with them.

    What keeps these things from rotating so that one is not higher/lower than the other? I thought that the posts on the bracket had a flat spot that fixed the orientation of the rubber bumpers to it, but they don't, so they can rotate. Especially where you are going to be orienting these to raise the front of the seat, seems like you'd need to measure to make sure you didn't have one side higher than the other. Or maybe eyeballing is good enough...

    You've put your finger on the critical weakness (IMHO) of this design, HD. Unlike the OEM originals, not only does the offset mount design make the bushings inclined to rotate under the shifting forces of the rider underway, but they can also rotate independently. This allows each forward mounting point of the seat to move forward and backward independently, also up and down independently, potentially allowing binding and/or a non-level, cockeyed seating position. No experience with the Wunderlich set up here, but by my experience (14 moto's, many off-road and DS), if something looks less than secure, it will be, particularly with lots of miles off-road.

    I have a '15 GSA. This ALSO occurred to me while considering a Wunderlich lowering set -- and off to the home shop (aka THE LABORATORY) I went to fix this apparent (justified by my experience) mistake of the evidently shortsighted Wunderlich design team... ;-)

    For no more than $2 (IIRC), I picked up 2 industrial grade hard rubber flask stoppers the exact length of the OEM rubber bushings. The stoppers were tapered, so the large ends were reduced to the same diameter as the small ends on a bench sander to match the diameter of the OEM set. I drilled offset mounting holes to match the approximate offset of the Wunderlich pieces. Now I had an equivalent set of bushings to the Wunderlich set with an important distinction. The new solid rubber pieces were drilled opposite and parallel to the mounting holes for a locating pin. I used a 4mm diameter stainless steel rod. The locating pin runs lengthwise through both bushings and is fixed in place through 2 holes, one drilled in each side of the OEM polymer frame that holds the bushing bracket. The pin cannot work out of place when the seat is in place but can easily be extracted by hand with the seat removed.

    No bushing rotation is possible and no need for another Wunderlich order. Road proven over 1K miles without a hitch, and there you have THE FIX. With a 30" inseam, the "lower than OEM low" position works perfectly with my OEM seat, which I have re-shaped, scooped-out and narrowed, dropping the height at the rear by approx. 1". The irritating OEM forward tilt is now 100% gone. This was a significant ergo improvement. At this point it's so comfortable I wouldn't change a thing.

    They are a tight fit on the pin. Once in place, and the seat installed, the seat capture "hoop" for lack of a better word, doesn't allow movement. They are stuck in whatever position they were in when installed.

    I got the Wunderlich ones to raise the front of the seat. This didn’t work well. 30 mins later they have rotated to the bottom.

    If I can find a 4mm rod like the Major I’ll see if that will hold them in place after I drill another hole

    Oh great, I just paid full nut for the Der Wunderlich version, over $50 shipped...but I like 'em.
    High setting on the front with an SC intermediate seat levels things out nicelt.
    Nice to have the adjustability.

    Mark, per my post above and your PM, these shots should clarify things.

    NOTE: this won't help you, since you're raising the seat height, but the holes I drilled for the locating pin happen to be located perfectly on both sides for lowering by the "V-ridge" in the polymer frame. Raising the seat above OEM high position would require a different way to fix the locating pin with the H-L seat bracket flipped over.

    This pin location is a perfect fit for lowering 10mm below OEM low, though. :thumbup

    I used the Wunderlich bushings to raise the front seat height and they work perfectly.

    Thanks for the tip Major ActionGeez
    With the seat bracket flipped over you could have the pin rest on top of the bracket. I used a screw as a temporary test but it has started bending already - the 4mm pin across the length of the bracket should solve the problem.

    I also have the Wunderlich ones to raise the front of the seat. If you are careful when installing the seat they will stay in place. Just came back from a 4000 mile trip and they didn't move from the high position. I have the seat extra high in front and low in the back and it really flattens it out with no slope toward the tank. I'm 6'3" with a 34" inseam and this setup works well for me. That 4000 miles was on the stock GSA seat, btw :D.

    This is extra high in front and low in back.
