Hello to All,
You all may already be aware of this, or even have a better and more up-to-date website for the Vulcan VN750 paint schemes, but here is what I found. This site covers the VN750-A4 (1988) through the VN750-A19 (2003) model years. I believe the first VN750 made its debute in 1985 and the good news is that they are still being made. Quite a longevity for any one particular motorcycle model.

by the way, as an update to the website that is mentioned the color schemes for the 2004, 2005 and 2006 models are listed here. I did not find the real color names of the 2004 model so those of you out there who own the 2004 will know and can enhance the list.
thanks,
