Popular Mechanics has an article on how director Christopher Nolan and his team of designers built Batman's new custom bike for The Dark Knight . & Apparently, it's a motorcycle-ATV hybrid driven by a stunt driver without the help of CGI. The article has all kinds of specs and discussion of exhaust and steering joints and things that make my eyes glaze over. & But I know you speed freaks and car boys (and girls) will like it. &
