So Cal must have been one of Ariel's most important marketplaces because we are blessed with a good number of these beasts rumbling around. Most all of them are strippers like this one. Stock Square Fours and the other Ariel models are rarely seen. What a wonderful sound these bikes make. First the mechanical whirring is captivating and the bellow that comes out of the pipes,especially through open megaphones is like nothing else. I imagine it sounds like Zeus's trumpet welcoming a warrior into Elysium.
