Development & Concept

In 1979, after five years’ development, Kawasaki spectacularly unveiled their new flagship model, the Z1300, designed to replace and exceed the ZI series.

With its water-cooled, 120ps, straight-six-cylinder engine and the weight exceeding 300Kg, it was truly a shaft driven monster. Huge like a warship, it failed to cope with the change of times and ended short-lived, yet this miscreant monster has a special ride quality. Although over forty years have passed since the classic bike’s release, its unique character has not faded and continues to mesmerize many fans.

Answering numerous requests of its core fans, after one year of research BITO R&D developed special super lightweight JB-POWER MAGTAN JB4 wheels which make the installation of the latest radial tires possible. Despite the front wheel being 3.2 kg and the rear 2.6kg lighter than genuine, MAGTAN still maintains rigidity and durability. By accomplishing a total weight reduction of a staggering 5.8kg, the handling changed dramatically.

A JB-POWER FCR carburetor, rear set, and brake system are other reasons this rugged machine maintains its reputation amongst bike lovers. Its silky and torquey straight-six-cylinder engine revs hassle-free over the entire rpm range, accompanied by the refined sound of the beautiful hand bend titanium exhaust system.

With the JB-POWER Z1300, comes a dream motorcycle, promising a supreme riding experience you will want to continue forever.
