Shaped for Speed

TECHNOLOGY
Shaped for Speed

As speed increases, wind resistance increases exponentially. To be able to operate in the ultra-high speed range, a combination of high power and slippery aerodynamics was needed. With power requirements taken care of by the supercharged engine, the next step was to design bodywork that both minimised drag and added control when riding at ultra-high speed.
It is no accident that the Ninja H2 does not seem to have the aggressive forward-canted stance of most modern supersport models. At the speeds for which the closed-course Ninja H2R was designed, such a posture would create drag that would hinder top speed aspirations. Instead, the stance is very neutral, almost flat—think Formula 1 car—to make the body as aerodynamically sleek as possible.

Aerodynamically-Designed Bodywork

Assistance from Kawasaki’s Aerospace Company was enlisted in creating the aerodynamically sculpted bodywork to ensure maximum aerodynamic efficiency.
The upper cowl uses lips and lines to help direct airflow over its surface, and positions the Ram Air intake in the most efficient position. It also incorporates a chin spoiler designed to generate downforce that contributes to high-speed stability.
The upper cowl’s shorter windscreen balances wind protection and appearance. The windscreen is about 35 mm shorter than the one used on the closed-course Ninja H2R.

Aerodynamic Mirror Stays

In order to maintain both straight-line stability and the control to change direction while running at high speed, a number of aerodynamic devices ensure the front wheel has strong contact with the ground.
Contributing to high-speed stability, the Ninja H2 features mirror stays with airfoil cross-sections. Like the wings on the closed-course model, they were also designed by Kawasaki’s Aerospace Company. Their trailing edges are equipped with Gurney flaps that increase the effectiveness of the simple airfoil shape, allowing greater downforce to be generated with a smaller surface.
