R15 REVIEW
R15 is the first model for the Indian market designed in the true supersport image and featuring a high-level balance of enjoyable running performance on winding roads. Packed full of state-of-the-art technologies, R15 boasts performance worthy of a supersport model and a body design that evokes the image of the YZF-R series and gives visual expression to the quality of its ride.
R15 is powered by 149.8cc Fuel Injected liquid cooled engine that will be producing an almost impossible 17bhp with maximum torque of 15 Nm at 7500rpm; which makes it like the most powerful bike under 200cc range and has a 6-speed Transmission. Yamaha is showcasing its potential for India with some real performance.
R15 has India’s first 150cc 4 valve engine with forged pistons, Deltabox frame & 6speed gear box. It’s overall length is 1995mm, overall width is 670mm and its wheels base is 1290mm. Since sporty YZF R15 is shorter too and its height is just 1070mm. YZF R15 features F 80/90 -17 inches tyres in the front and 100/80-17 inches tyres in the rear. Both the tyres are tubeless.
Design & Styling
The “R” Design: This characteristic of motorcycles designed by Yamaha as represented by the R series reflects the philosophy running through these models — expressing performance visually.
For example, YZF-R6 shows a strong body line that springs up in a single line from the rear axle to the pivot and then to the head pipe. This is a visual expression of the straight shape of the Deltabox frame. These elements are a visual expression of “frame rigidity.” Viewed from the side, the shape created by the side panel and the upper surface of the tank creates an impression of the center of gravity shifting to the front tire.
This is a visual representation of how the front tire grips the road in its sporty running performance. Needless to say, YZF-R1, with its athletic build, is also a visual expression of performance. A characteristic of the R series is that, when you view the machine, you get a sense of its concept and performance.
This philosophy has been fully transmitted to YZF-R15. An important point to note is that this motorcycle is not a scaled-down version of YZF-R1 or YZF-R6. YZF-R15’s design is based on having an excellent engine cooling method.
The shape of the cowling around the radiator area was determined so that the shapes of the air intake area and the rear outlet area where the air is scooped out are optimized to improve radiator efficiency. As for the outlet area, the mid-cowl area was designed using sculpturing 3D methods to create a three dimensional shape with a sense of volume. rst for the Indian market.
When viewed from the front, it gives a sense of volume that seems well beyond its 150cc displacement. This does not simply mean that it is voluminous, but that it is grounded in the Art of Engineering which transforms function into art.
Engine
YZF-R15 is equipped with this all-aluminum cylinder called the DiASil Cylinder and a forged piston, the same type of piston used in Yamaha’s supersport bikes. The fact that both the piston and cylinder of YZF-R15 are all-aluminum ensures excellent heat dissipation, eliminates heat-induced engine power loss, and helps improve fuel
