Since its first release in 2008, the official book of the Superbike World Championship has been an indispensible resource for all fans of the championship reserved for production derived bikes, the championship for bikes you can buy from your local dealer. Like every year, this book opens with a chapter devoted to the winner of the World Championship title. Plenty of space has been devoted to reports on the 12 scheduled races of the 2015 season, and to the bikes and riders that constitute the fundamental pieces in the complex SBK jigsaw. The "strong suit" of the official book, one of the parts that will delight fans of the series, is without doubt the one dealing with the engineering of these authentic jewels, described in the most minute detail - thanks to the contributions of specialists working for the various teams - and illustrated with numerous photos revealing all the secrets of the championship's leading players. The chapters on the "other world championships," Supersport and Superstock 1000 and 600 complete a book that should be on the shelves of every true fan.
