When the bike is clean you cant beat the Vivid Black. I still love mine and would stick with Vivid Black again just because it looks so sweet when clean. Now you ride it for 10 minutes and its dusty. Especially on the rear saddle bags and the rear fender. I have a mini california duster that I keep in the saddle bag to keep the dust off. Its kinda a double edged sword. The darker the paint, the better it looks when its clean and the chrome really shines, the lighter the paint, the less the chrome stands out etc but maintains a better look when its dirty.....it really boils down to "your" personal preference.
just give it a 5 minute wipedown with pledge after each ride. I use the mini duster occasionally, I don't clean the livin daylights out of it real often, it's for riding
