I prefer riding in suit and tie. Nothing says success like a man on a harley in a suit.
I wear black when I work on the bike or car. It also helps cover the tool shed I bult up over the yrs. And if you really can't find colors other than black you are not looking hard enough. I have a beautiful long sleeve from Grand Canyon Harley that's a light brown. I also have one from SJ Harley that's red.
