Harmony between rider and machine.� YAMAHA's Human Technology involves studying the form of the motorcycle actually in motion with the rider on it. The R series is the embodiment of 1) a wide frontal space that protects the rider, 2) an easy to ride seating area that gives riders the freedom of movement and allows them to steer effectively, 3) the glamorous tail treatment that takes into account the management of airflow behind the rider, and 4) a sensual racing form that brings all 3 of these elements together in a harmonious package. These characteristics have been splendidly reproduced in the YZF-R15 version 2.0.
