"Kawasaki.com" said:All V-twins present engine heat challenges, especially full-dress models with leg shields, since the rear cylinder and exhaust pipe are almost directly under the rider. Kawasaki is the first manufacturer to provide, as standard equipment, an effectively designed air management system to help increase rider comfort at a stop.
The primary part of the Kawasaki Air Management System (KAMS) routes radiator heat to the ground, below the engine, while the secondary part of the system draws heat away from the rear cylinder and exhaust pipe and directs it to the ground on the left side of the motorcycle. This system is particularly effective in warm weather while stopped in traffic or for extended periods of low-speed operation, such as during staging for group rides or parades.
