The 2002 to 2005 forks are 3/4" (19mm) longer than the 2006 and newer model years that use radial brakes.
Attached 2006 and newer OD dimensions workup is by member rij1 (I don't have a workup for 02~05).
Both use 41mm OD lowers.
I actually do not have reliable length dimensions for either stock model year fork setup. And none for the tube diameters or lengths used in the R1 fork swap either. The overall length from the top-of-upper-to-axle-center dimension, and the overall length from top of upper to bottom of lower. The only manual dimensions are uncompressed spring length and travel.
I only mention these because in many cases sellers do not realize the difference between Road Star and Road Star Warrior, it seems strange but it's true. Pictures or drawings will show it right away. But individual component part numbers should be verified for fitment.
I wish I had a known Outside Diameter image like this for the early models. I've been told they are functionally identical. My guess has been the 3/4" (19mm) length difference is all in the 41mm lower, but I have no expert hands-on documentation.
I realize this photo is not your model year.
