The YZF-R15 body with its close resemblance to the YZF-R1

So, what were the specific design intentions for the YZF-R15?
We first asked the designers about the characteristics of the definitive cowl around the radiator. "For the YZF-R15 we first designed a cowling shape around the radiator that would make maximum use of the running airflow. To maximize the efficiency of the radiator, it is not only important how you design the shape of the front end where the air is drawn into the radiator but also the shape of the rear end, where the air is blown out and away. This is of course another area where experience from the R series model development was utilized.

This is the reason why the central cowl area has a somewhat sculpted, 3-dimensional shape that creates a sense of volume to the machine.

Another design element that reveals this model's R series DNA is the ‘two-eyed' headlight assembly. "Regarding these headlights we created them as a unit that was faithful to the R1's design in terms of the bulb structure and the inner portions. The YZF-R1 and YZF-R6 have a front mask design with surfaces structures in a way that actively cuts through the wind. We designed the YZF-R15 front also in this image of charging forward through the wind. This is another case of giving visual expression to performance," they add.

"Another defining characteristic of the R series models is the appearance of its form when it is actually running. This is reflected in elements like wide front space that provides wind protection for the rider, the sitting area that is slim and also offers a wide range of movement for greater ease of rider movement and machine operation and the design of the tail area with its concern for air management behind the rider. These are elements that faithfully reflect the design individuality of the R series models."

Other than these, there are impressive elements like the digital speedometer, the separate panels and the racy image of the area around the meters that project a look of quality and the exhilaration of the racing spirit.

But what is it that made this kind of design development possible?
"It was possible to a large extent because of a constant sharing of information with the actual YZF-R1 designers and the fact that they used the same modeling room for their design work. So, it is only natural that the design of the YZF-R15 should reflect the heritage of the R series so clearly," they conclude.

However, when you look closely, there are also a number of differences between the YZF-R15 and the YZF-R1. And surely there are sound reasons for the differences too, deriving from the actual need of the YZF-R15. But details like these are among the many secrets of t
