Designed as Kawasaki's response to the ground-breaking Honda CB750 of 1969, the Kawasaki 900 Super 4 Model Z1, affectionately referred to by many as the 'Z1000', appeared in 1972. It took the motorcycling world by storm and has a strong claim to be the world's first true ultimate superbike. Thirty years on, the (K)Z1000 Z1-R has emerged as one of Kawasaki's most desirable and sought after collectables from the 1970s. This book will help the reader appreciate the ever-evolving Japanese motorcycle styling and the introduction of various technologies as standard equipment, and just how sensational and unique these motorbikes really were.
