I thought you said this bike was great pretty much out of the box?
Other than the POS factory air shocks the bike is great out of the box.
Many like the air shocks. I hated them. I could never set them were the bike felt planted in the corners. The bake of the bike in hard corners felt like it was wallowing or mushy and loose. Could be I was so use to 944's on my 09 CVO Road Glide, then the HD hand adjustable premium low profiles on the 12 CVO Road Glide and the 13 CVO Road King that these just did not fell right to me. Once I put the Ohlins on it the back feels every bit a planted as my 12 SERG or 13 SERK, if not better.
