Yamaha YZF-R15

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.

“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.

 

Additionally, the designs were developed in the same modeling room where YZF-R1 designers worked. Information was shared, ensuring that the R lineage would be transmitted. In addition, the model also incorporates a multitude of adjustments for the Indian market including seat shape that allows for tandem riding (integrated with the main seat), tandem grips that are easy to grip and also contribute to the supersport design, and a riding position that takes into account comfort, etc. In other words, the YZF-R15 is characterized by a hybrid design that combines the world-class design of the “R” series with localized functions. The YZF-R15 was created to lead the supersport category in India.
