In 1973 Kawasaki introduced the Z1, a motorcycle which is considered by many to have ushered in the era of the modern superbike, After its introduction it earned the nickname “The King”. The combination of a 903cc engine, dual overhead cams and high power combined with integral styling of tank and body pieces to create a motorcycle for the masses that had never been seen before.
All other manufacturers had to change their mindset to keep up with popularity of this motorcycle. By the end of the decade all Japanese manufacturers had developed machines to rival the Z1 which were almost direct clones of its engine configuration and integral body panels.
These bike wars directly lead to the demise of the flagging British motorcycle industry. The American motorcycle industry (mainly Harley-Davidson) was also on its last legs and was only saved by radical restructuring and inventive financing.
