Difference between Rockster speedo and R11s

[vladecvc]

Gentlemen, does anyone know if there is a difference between the rockster speedo and the R11 S speedo?

I don't have your answer but here's a nice photo courtesy of inmate r1100sp .

Hey guys.

Although I did not take a photo of the back of the Rockster speedo, (white face) memory tells me it appeared identical to my R1100S speedo. It sure seemed like the two parts differed only in the color of the gauge face.

However, the wiring harnesses attached to the instrument cluster assemblies are slightly different. The Rockster harness has (2) electrical connectors that plug into the bike - visible in a couple of my photos in the link furnished by Groceryrun. (thank you, sir) My R1100S harness has only one connector. But, the myriad of wires leading to the speedo, tach, all the bulbs, etc., on the back of the shell (white) of both clusters are identical...also visible in the photos. The black covers and white shells of each cluster assembly are identical.

Worth noting: when I installed my R1100S harness onto the Rockster cluster (again; req'd due to the connector difference) and started the bike, the tach worked correctly. The two speedos also appeared mechanically identical but I suppose we can't assume the Rockster speedo would work on my S...as it was very dissassembled on the centerstand in the garage. But I'd put $ on it!

Hope this helps vladecvc.

For what it's worth... A few sub-par shots of our tach.

Check the part numbers at realoem.com

If same, parts are same. If not, they're not.
