Got my 13" ST 's on today and road 90 miles, just me, thru my local back roads and some known spots where stock shocks made me wince but not so with these, happy thus far!! Big improvement 1-up we'll see how they fare 2-up later. HD-Dude took care of me, if going to buy some, email him. I'll post my opinion when I do a run with 2-up & luggage.
In my opinion these ST's are great! Major improvement over the stock air shocks. They have surprising proven to be great in 1up, 2up & fully loaded touring.
This was an easy DIY install. My only whoops was I had a Wheeldock center stand and the added heigth (~1/2") made that unusable. But called Wheeldock and they were great, they knew hwo to handle the upgrade, for $50 I sent it back to them and they welded and repainted with the added 1/2" heigth and now it works great again.
