Took delivery, and installed them last night. These are really, really nice units. The pics on Rivco's website do them no justice at all. Box states 1 5/8" back, and 5/8" up from OEM stock riser position. I didn't have a chance to compare one side-by-side with the stock riser, but let me tell you they put the SpeedMaster bars right where I needed them with the Corbin seat setup I'm using. These FREAK'N ROCK!!!!
Rode into work this morning with the new shiny risers installed, and I think I've gone to heaven. What a difference these have made.

I'll get pics posted on my website ASAP for you Ed. Thanks a bunch my friend!!!!!!! YOU-DA-MAN.
