This voluminous book zooms in with a tight focus on an anomaly. The briefly successful and controversial period of the nineteen-eighties and nineties when Honda shattered Harley-Davidson's long held monopoly on the venerable and uniquely American sport of dirt track motorcycle racing. "Has there ever been a research project as voluminous as this, focused entirely on dirt track racing?" Asks Dave Despain in his foreword. "I can't imagine" was his response. Its strength would be that the story is told largely in the form of 60 plus interviews with some of the participants, and the detail pulls the reader in. A large selection of photographs accompanies the narrative along with copies of period journalism, much of it from Cycle News. In addition, expanding the story beyond Honda-versus-Harley, there are a number of sidebars which delve further into the minutiae of the period. These are readily available on the Motion Pro website (www.motionpro.com)
