Overview Of Yamaha R15

Yamaha 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.

Yamaha 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.

Update: New Shades & Graphics For Yamaha YZF R15

Yamaha have spruced up the looks of R15 with introduction of new colors and body graphics. This new makeover adds a punch to the sporty looks of the bike. R15 is now available in four new colors namely “Impact Yellow”, “Midnight black”, “Sunset Red” and “Racing Blue.”

Apart from the new Yellow shade Yamaha R15, the tone of the red color has also been changed and is different from the previous red color. Similarly there is a slight difference between the black and blue colors from their previous variants. The red colored bike now also has the side flaps of the same color. The previous version had the black side flaps. The Yellow color has white colored side flaps and the paint quality is very good on it.

There is a new design on the side flaps which extends to the tank of the bike. There is a new R15 sticker above the left headlamp. Yamaha has also provided the rim stripe tape in the Yellow, red and black bikes. The ex-showroom price New R15 is around Rs 2,000 higher than the previous version which comes to around 99500.00 (Ex-Showroom New Delhi).

Design & Styling Of Yamaha R15

Yamaha R15 has all the characteristics of motorcycles which designed by Yamaha to represent the R series which 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 of Yamaha R15 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, Yamaha R15 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 Of Yamaha R15

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 efficiency. The DiASil Cylinder is given a special surface treatment to prevent oil evaporation from the cylinder’s surface and improve oil consumption. The cylinder also has excellent hardness and is considerably resistant to wear compared to conventional iron sleeves.

Additionally, the piston of Yamaha R15 is made in a forging process, the optimum way of achieving lightweight designs.The reciprocating mass with the forged piston is approximately 20% less ( according to Yamaha test ) than with an engine of the same displacement fitted with a conventional cast aluminum piston. Resulting in an invigorating feeling when revving up. Conventional pistons are typically made in a casting process where molten aluminum is cast in a mold.

Yamaha developed its proprietary “controlled forging technology” in 1997, which enables mass production of forged aluminum pistons. These pistons have been used in sport models such as the R series. The same manufacturing process was used to develop YZF-R15. Forged pistons retain the excellent strength of aluminum alloys because the metallurgic matrix of aluminum is not affected during the fabrication process. Therefore, the piston can be made lighter and thinner.

Chassis Of Yamaha R15

YZF-R15 is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out. In particular, it reduces annoying “sinking” when riding tandem. The linked monocross suspension consists of a link mechanism sandwiched between the rear arm and cushion unit to create changes in the lever ratio based on the lever effect. When the shock absorber is almost fully extended, the lever ratio is high and therefore the spring is soft, and the damper works softly as well.

As the shock absorber strokes in, the lever ratio of Yamaha R15 gradually decreases and the spring rate increases. Eventually, when it is nearly fully stroked in, the lever ratio becomes small and the spring becomes hard and strong. The damper also becomes hard. By making changes to the lever ratio in this way, we were able to achieve soft riding comfort as well as excellent damping under intense load conditions.

The optimization of the frame and rear arm rigidity of the Deltabox Frame of Yamaha R15 combined with the effects of the linked type monocross suspension achieve good riding comfort, agile handling, and turnability, hardly ever causing bottoming out. In order to maximize the efficiency of the fuel injector, which injects the optimum amount of fuel for different amounts of intake air, YZF-R15 is equipped with a large 3-liter air cleaner. The duct area of the intake duct was designed optimally to optimize the flow of intake air.

Additionally, the use of a 4-valve combustion chamber (a combustion chamber with 2 intake and exhaust valves each) has allowed designers to layout the spark plug at the center of the combustion chamber for better flame propagation. This also increases the total valve area relative to the 2-valve chambers for improved intake/exhaust efficiency (volumetric efficiency). YZF-R15 is fitted with a hemispherical 4-valve combustion chamber, a configuration that allows intake and exhaust valves to be laid out in the smallest size possible.

YAMAHA YZF R15 Details

Much awaited Yamaha's YZF - R15, a 150 cc sports bike is finally out on Indian roads. The bike today announced by Yamaha Motor Pvt. Ltd. contains true Yamaha Racing DNA. The bike, Super Sports Yamaha R15 is expected to set all new standards in design  and performance in bike Industry of India.

Machine, ie. the bike has technology percolated from R1.  This new bike YZF - R15 has many firsts to its  credit on Indian road  including first liquid cooled engine, 4 valve fuel injected engine etc. The YZF R15 is powered by 149.8cc Fuel Injected liquid cooled engine  producing 17bhp with maximum torque of 15 Nm at 7500rpm; which makes it like the most powerful bike under 200cc range. Yamaha YZF R-15 boasts 6 speed gearbox with optimized gear shift ratio so expect a smoother ride.
The bike will be priced at Rs 1,14,600 on road (may vary depending on locations).

The bike was recently showcased on Race Track on Chennai. Bike was impressive and attractive.

     

We will now talk about various aspects of the bike one by one.

Looks and Design

If you are not a bike enthusiast  but still have some interest in bikes  even then  you will Yamaha YZF R15. And if you happen to be a person who is little aware about bikes around the world then you sure know that we have a DNA of Yamaha YZF- R1 on Indian roads. The bike is directly derived.. rather say inspired from R1. Just to add here, Yamaha YZF R1 is globally acclaimed Yamaha bike and has a fair respect around the world. So Yamaha, by introducing / developing a bike derived from R1 is like giving Indians what they want. Indian bike market is still in initial stage.  So giving R15  is like giving taste of international standards and styling to Indians but on the cost which is in their reach. When I say that design is inspired from R1 then there is really nothing much left to say as we know about the success and design of R1 very well, however, in layman's language, bike has stunning looks.  Company says that they have a "R" characteristic in their design which is adopted in R15 too.

From company's website explaining about their R factor : "“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. "

Starting from the headlamp, the R15 dual sharp head lamps clearly reflect the yamaha R1 in it. However, it still manages to distinguish easily from R1.  

So you may see that right from the beginning they had R1 DNA in their mind. However the R15 is not scaled down version of R1 and it is clearly distinguished from R1. The R15 has more practical design as per Indian perspective. They made sure that bike looks international as well usable in India perspective too. The bike has some good details, however they adopted it to be more curvy than having sharp design of R1. Side cowl ar impressively designed to cover small engine (150 cc) of R15 and nicely placed. However, engine would have looked even better if it was body colored or black. 
The bike sports digital console and speedometer. Tyres are tubeless.

 Riding position is all sporty. One would feel sporty the moment you take seat on bike.  As hot now a days, the bike sports split rear grab rail. Looks cool. However, real side indicators could have been more sporty. They just look so basic and give little feel of out of theme. May be because of little simple back of R15 as compared to its front. But overall, it makes decent impression.

Engine
The Yamaha YZF R15 is powered by 149.8cc Fuel Injected liquid cooled engine  producing 17bhp with maximum torque of 15 Nm at 7500rpm. So consider it as return of evil that we had once saw many years back in Yamaha's  bike and for which Yamaha was famous in India. I still see that people rework on old Yamaha bike and use them even they are out of production because they remember and like that power image of Yamaha.

R15's engine is liquid cool, its first in India in bikes. The technology is widely used in four wheelers etc but its hardly their in bikes of this niche. Being a liquid cool engine, it ensure better engine performance even on power ride and on long ride. So bike has a small radiator in it. Moreover, being liquid cooled, it also helps in reducing engine noise so deliver even smoother ride.

Also, Yamaha has implemented new DiASil Technology which makes engine more efficient in power handling. DiASil Cylinders are all-aluminum cylinders made by YAMAHA’s proprietary aluminum die casting technology. An aluminum alloy with 20% silicon content is used to create a very hard, reliable cylinder surface, making conventional iron sleeves obsolete. As a result, the entire cylinder can be made of aluminum, a better conductor of heat, which means the cylinder delivers better heat dissipation and less weight. (Aluminum’s heat conductivity is 3.1 times that of iron.)

And the piston used in R15 are  made in a forging process, its a Yamaha's own proprietary "Controlled Forging" which makes piston lighter and thinner yet more usable.

Engine uses Fuel injecting technology with 3 ltr air duct and providing improved combustion ability hence efficiency.

Overall, engine is power packed and highly optimized. Surely gonna make you rock.

Chassis and Suspension

YZF-R15 is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out. In particular, it reduces annoying “sinking” when riding tandem. And the Chassis is derived from their experience of MotoGP and they call it Delta box frame. Company describes it as :

" This type of frame is currently used in YAMAHA’s R series of sport models. The engine is mounted on rigid supports; one on the head side and two on the case side; so that the engine itself becomes a structural member contributing to body strength and rigidity. The engine’s low vibration makes rigid supports possible, ensuring low vibrations and excellent balance of rigidity."

Mileage

As a performance bike, do not expect a decent mileage, being a 150 cc bike , only expect 35kmpl to 45kmpl of mileage.

In the Last

It looks like real performer from Yamaha after a very long period  and surely it will going to revive their performance image in Indian market which they lost a while ago. By launching R15 in India, Yamaha gave Indian a glimpse of the international standards on Indian price. However, priced little heavily otherwise their no other cons of this bike which I could find. Riding comfort, engine responsiveness as well whole layout is neat and attractive.
