Motorcycle Handling and Chassis Design: the art and science by Tony Foale (Repost)

Mr. Foale's book is a hugely practical treatise on the subject of motorcycle chassis design– and the only worthwhile one I know of other than some very technical SAE papers from the 1970's on modeling and simulation of motorcycle handling.
Mr. Foale's insight into the incredibly complex dynamics of motorcycle handling chassis design, and tire (sorry, Tony– I just can't bring myself to spell it "tyre")/chassis/rider interaction comes from decades of building and riding specialty and adjustable-geometry frames to test out theories, and in more recent times, instrumenting motorcycles to validate and refine dynamic models. He's NOT guessing (and while this is not unique in motorcycling, it is rare to say the least!), and his dedicated pursuit of the truth is both admirable and hugely valuable.
This book is technical, but it also presents the material in such a way that, if you're curious enough to have asked yourself why your motorcycle behaves as it does, you will probably be able to understand and appreciate the book's presentation.
This book won't tell you how to fabricate a motorcycle frame and suspension, but it will tell you why some geometries work and why others do not in a given situation, and give you practical, applicable design guidelines and theory. It is not a prescriptive description of how to tune forks and shocks, but it addresses how the suspension geometry, settings and function impact the bike's behavior and helps you think through how to sort out handling issues for street or track. It does not address design for strength, materials selection or provide much on chassis flex (and in the modern motorcycling era, chassis flex is a vitally important design attribute/choice), but it gives you a great perspective on the history of frame and suspension concepts, with very interesting insights on why some really superior approaches have not been deemed economically viable by the major motorcycle brands.
