The ID Says You Need A Dozen Bikes, But The Ego Knows Better. Take One 600cc Sportbike And Make Yourself Comfortable On The Couch

Ergos Explained
In"Voyage of the Beagle," Charles Darwin was just starting to clue into his theory of natural selection that he let flower in "The Origin of Species." So try not to mind as we evolve our own ergonomic templates and measurement processes. After some extended noodling, we've decided to slightly alter the way we measure the seat-to-bar distances. Rather than from a central point in the middle of the seat, this measurement is taken seven inches off the centerline of the bike. This provides a more realistic indication of the reach to the bars.

In addition, we've added a new measurement called handlebar rise. This linear figure gives you the distance the handlebars are above or, God help our backs, below the level of the seat. For clarity, we've removed the third leg (from the bars to the pegs) of the seating triangle.
