Idk if it counts as contrary, but in the us there is an entire parallel/mostly separate black biker culture. Segregation still existed legally when biker clubs were first becoming a thing, and even for years after black riders were excluded from the private clubs formed by white people. So obviously they formed their own clubs, ran their own bars and hangouts, and even their own rallies to rival Sturgis. Women also make up a way bigger proportion of black motorcycle riders in general (up to half at some events) which is kind of cool too
