Kawasaki Performance Inline-4 Engine

Kawasaki's inline-four engine lineage stretches from the 1972 Z1 through the ZZR1100 to the supercharged Ninja H2 — a continuous development of the same fundamental architecture spanning five decades. The ZZR1100's 1,052cc unit defined the hyperbike era; the Ninja H2 uses a 998cc version of the same architecture with a Kawasaki-built supercharger bolted to it. All share the same basic DOHC inline-4 geometry.
