YZF R15 - Racing Instinct

Racing Instinct. - Passing on the "R series" DNA


Humachine Technologies & Sensual Racing Form

The YZF-R1 and YZF-R6 are equipped with under cowls that are based on the image of a diffuser, to give them the best form for aero-management. These are not cowls for simply enclosing the engine, but forms composed of blade surfaces that actively control airflow. This spirit has been directly inherited by the YZF-R15 version 2.0.

"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.

The YZF-R15 version 2.0 is a new model that has been developed under the concept of a "Graded Up R15". While maintaining the proven ease of handling of the existing R15, the R15 version 2.0 boasts of spruced up looks and better performance in circuit riding. The design elements are borrowed from the supersport model YZF-R1 that is adapted from YZR-M1 MotoGP race machine.

The YZF-R15 version 2.0 is a 150cc liquid-cooled 4-stroke fuel injected bike. The R15 version 2.0 has undergone changes as compared to the present YZF-R15 in the specs of the Engine Control unit (ECU), drivetrain unit, a long aluminium swing arm, wider front and rear tires (radial tire for the rear), split seat, LED taillights and new-design middle cowl & tail cowl.
