Its like blonde or redhead, each can be hot as hell, its all preference, I prefer vivid black, But I could have the sunglow red on the side and be pretty happy.
Everything I've ever owned has been black including several HD's but I have to agree with Harleyghost... When I went to but my 09' S. Glide I was going after Vivid Black until I looked at the Redhot Sunglo... It was almost spiritual... I bought the red one and haven't missed black since...
I've have both red and now black. The black is harder to keep clean but lets face it cars, trucks or motorcycles look the hottest in black. Red is for sissies
I Love both Black and Red, and when I bought my first HD, the sales guy who I knew said ..."go red, everyone has black, imagine pulling up to a bar and seeing Black, Black,Black,Black, Black,Black, RED, Black, etc". what he said has mostly proven true! haha.
