The YZF-R15 and FZ16 were developed with the aim of going beyond the conventional commuter bike and to achieve true sports bike' performance that offers the owner the real fun of riding. With the YZF-R15 we have achieved performance that can' e thoroughly enjoyed not only on the streets but on a race circuit as well. As for the FZ16, it takes the same sporty technilcal concept of the YZF-R15 and translates it into a model with a simpler air cooled engine to create an attractive street machine with something extra to offer riders. That something extra is a wider band of powerful torque for truly dynamic performance plus looks that give the added value of pride of ownership.

Both the FZ16 and YZF-R15 have performance features including a balancer, rocker roller arm and offset crankshaft. Also things like optimized piston rings, all for the purpose of improving the three factors that effect engine performance most: intake/exhaust efficiency, combustion efficiency and reducing the horsepower loss. The major factor contributing to an invigorating acceleration feeling and passing performance in a motorcycle is the optimized inertial mass of the crankshaft. The relationship between the inertial mass of the crankshaft and the engine displacement is called the IV ration, and it is an important factor effecting drivability. That is why concerted efforts were made to optimize the IV ratio on the FZ16 along with optimizing the cap setting. The combined result is acceleration with a good sense of pulse and strong torque characteristics.
