Harley-Davidson riders are quite loyal to the brand. That means they love what they ride and will rarely turn to look at other bikes, let alone a metric cruiser motorcycle. So, making them look twice requires some special aspects. Road presence is certainly the most important. The cruiser needs to be large and long in a different way. The design should also put the V-twin engine on full display, preferably in a shiny finish that gleams in the sun. Bonus points if the design is aggressive and rare rather than being retro like we usually see on cruisers.
