Laam seat, Wilber's Shocks from 2012 GS
I had a 2011 factory low GS that I used for touring. I had Seth Laam do the seat for my 170 pounds and 30" inseam. I also installed Wilber Shocks from Ted Porters Beemer Shop. These shocks lower a GS by 25mm and a 2006-2013 GSA 50mm. Then I found a factory low R1200RT so I sold the GS. The shocks were installed January 2017 at 77,000 miles. I had Jeff at Ted Porters revalve the shocks and put a slightly firmer rear spring on at 85000 miles in March 2017 as I felt the ride was too harsh which is normal for Wilber Shocks. I reinstalled the shocks in April at 86000 miles. I took them off at 88000 miles when I put the GS up for sale. Ted Porter suggests rebuilding the shocks every 2 years or IIRC 24000 miles. These shocks should need nothing as they only have 2000 miles of use. A rebuild costs $180 per shock.
I will sell the seat for $275 shipped in the lower 48. A Laam rebuild on your seat is $399
I will sell the shocks for $700 shipped in the lower 48. New price is $1437.
