Harley-Davidson XR-750
<p>Harley-Davidson's XR-750 has ruled dirt-track racing for more than two decades. In fact, no other race car or motorcycle has won as many races over such a long time period. And the victories continue today. </p> <p>This is the story of the legendary XR-750 from its development in 1970, when it was created to replace the aging KR. The first XRs used iron cylinder heads and barrels-and were painfully slow. By 1972, the motorcycles were redesigned with aluminum heads and barrels, and the XR-750 took home the trophies. </p> <p>Found here is the development of the XR-750 with a technical analysis of the complete motorcycle, detailing specifications, modifications, innovations, and aftermarket components. </p> <p>This is also the story of the men who designed, tuned and raced the XR-750. It was their engineering skill, iron-willed riding and tuning secrets that made the motorcycle a winner. The ranks include Jay Springsteen, Dick O'Brien, Bill Werner, Scott Parker, Cal Rayborn, Mert Lawwill, the Brelsford brothers, Gary Scott, Ricky Graham, and more.</p> <p>The book is divided into three parts, the motorcycle's development, the season-by-season race championships, and how the pros make the bikes go-and go fast. More than 300 photos tell the inside story of the XR-750 on the dirt track, the XR-750 and XR-1000 on the street and XRTT on the road-race circuits. </p> <p>Allan Girdler writes of the Harley-Davidson XR-750 with passion, enthusiasm and firsthand experience. He brings his straight-talking technical writing and colorful story-telling to the history of the XR-750. Girdler is a former <i>Cycle World</i> editor and author of many books including <i>Harley-Davidson Racing 1934-1986</i> and <i>Harley-Davidson Sportster. </i></p>
