I've got the Works Street Trackers w/ BARS system for adjustment. I went with the 13" version vs the 12" which are OEM on my 08 SERK. This raised the rear by just under 1/2". These have been very good shocks and are extremely easy to adjust for two up / loaded for bear riding.
I had the Ricor Intiminators installed in the forks on my 02 SERK. All I can say is I am very impressed with the improvement this has made. Much less dive during breaking, handles expansion joints and the likes with ease, and she seems to track thru curves better. For a $150 gamble on something I did not think would make much difference, I must admit I was wrong. They are not Traxxion Dynamics but they also cost a great deal less.
I've been so impressed with the Ricor Intiminators, I ordered a set of the H. D. Touring rear shocks. Just like the Works folks, I had to give them a lot of details on my weight (OMG I weigh that much and am that short!!) style of riding, gear on board, etc. These are build to order so I do not have them yet but will post on them after I give a try. They are going to be mounted on the 02 SERK. She be equipped with a Ricor Suspension front and rear.
If anyone needs HD 12" air shocks, I've got two sets in the garage, let me know.
