The bevel-drive 860 and 900 was one of the most significant motorcycles of the late 1970s, providing a unique combination of power and handling that was unequaled by other motorcycles at the time. When Italian car stylist Giorgetto Giugiaro penned the 860GT in 1973 few would have believed it would evolve into one of the greatest Ducati line-ups of all time. The square-case 860 become the legendary 900 Super Sport, Darmah and eventually the Mike Hailwood replica, built to honour Hailwood's spectacular comeback victory at the Isle of Man in 1978. The square-case Ducati engine eventually lasted more than a decade, sustaining the company through a downturn in the early 1980s. This book covers every incarnation of this great model, from the first 860 through until the final Mille. Illustrated with 200 pictures and with complete appendices of technical specifications this book is a must have for any motorcycle aficionado.
