Harley motorbike best for a biker/scariest looking?

[Abigail]

I'm writing a book, but I have no idea about motorbikes but for a character I want him to ride a big black scary looking harley biker bike but not sure what model? It has to be kind of ominious looking, he's a kind of hot badass character? Any ideas?

Thank you!!
I actually think I'll go for the triumph rocket 3 with a supercharger!
