Designed to settle the issue of supremacy in the flagship class once and for all, the ZZR1400's new engine boasts an increased displacement and thorough engine tuning to deliver heady levels of power and unrivalled acceleration. The step up in performance over its predecessor is readily apparent, with more available torque across the rev range and substantially higher upper-end power. And with the notably stronger acceleration, twisting the throttle past 4,000 rpm may result in a sensation not entirely unlike that experienced by astronauts breaking free from the Earth’s gravitational pull.

4 mm longer stroke increases displacement of the powerful In-Line Four engine to 1,441 cm³. Bore and Stroke are now 84 x 65 mm.
Compared to its predecessor, the new engine offers more torque at all rpm, and substantially more power in the mid-high range. Acceleration from 4,000 rpm and up is notably stronger. Torque is strong enough to pull away from lights in almost any gear: at 2,000 rpm there is 9.5 kgf.m of torque available! And this figure jumps significantly from 3,000 rpm.
