Seat Height Lowering Kit

Kit does what it says but I find it unusable because it changes the slope of the seat. The front is angled down and I found it uncomfortable. Removed the item after first ride.

I love Wunderlich products and the folks at Wunderlich America, in CA, are the best! I bought (2) sets of these. One for my '15 GS and one for my '17 RT. I've only installed them on my '17 RT at this point. Here's what I found... If you rotate the Seat Height Adjusters to the point that puts the seat in the lowest position, you end up with a large gap between your seat and your tank. Not a good look! I moved the "eccentric" to various positions, in an attempt to get an acceptible gap between the seat and the tank. When I found the "sweet spot" it only lowered the seat 3/16" or 4.76mm, which is about 50% of what I was hoping for. Every little bit helps, but 4.76mm is such a small amount, I honestly cannot feel/tell any perceivable difference. I've yet to install the second set on my '15 GS. Hoping I'll be able to get the full 10mm without creating a large gap between the seat and the gas tank. I'll update this review if I succeed. Hope this helps!
