New Yamaha YZF R15 | Review, Pictures & Specification (150cc Bike)

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 INR 97,425 ex-showroom (All India).

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.


Engine of Yamaha YZF R15


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.

Hello, I am a Tech Specialist in a MNC in Noida and a great byke lover, I am riding since the age of 9 and I am 29 today.
I have completed 4000 Kms on R15 and using it since a month.
I totally agree that when I first made up my mind to go for it, I thought it must be a something more powerful (when it comes to pickup).
But I would really say that its far more better than any other Indian Bike in the market.
Having used both Karizma and Pulsar .
And I will like to share my outlook;
1. I have travelled straight from Lucknow to Delhi having only two stays in between thats about 200 kms of non stop riding at a speed of 75-80 on avg. (coz of its DIasil cylinder and Forged piston, cilinder has 20% silicon which keeps it cooler than rest of the bykes.)
I dont think any other Indian Byke can do that, it will burn out and the clutch plates will cease.

2. It has given me amileage of 45 km/lt on highways and 38-40 kms/lts in City.I n which I have operated it around to 135 km/hr at times.Which means Its best in its class.
2. It has an awesome grip on roads, its not important for a bike that it goes past 130-140 what is important its that how much safer it is to go to that speed. Toy can really feel safe at speeds of 120, the byke will not skid when applying brakes as that speed.
Some people say that it has narow tyres, they were specially made for R15, having soft rubber and different raddi, complete tubeless providing 3 times better grip that Pulsar and about 2 times better that Karizma in my view.
Before riding this I loved Karizma, coz it was better than Pulsar, but those two feel to be pieces of srap of primitive machines when comapred to R15.
Dont check the speed and pickup. Ride it above 120 km/hr you will forget about the price and comparisons.
