Though it may not appear so, the dip in performance has an upside too

The fourth generation of the YZF-R15 made its global debut starting with the Indian market. While the V4 scores high compared to R15 V3 in terms of equipment, the slight drop of performance had everyone bewildered. But as it turns out, Team Blue had a very good reason to do so.
The VVA (Variable Valve Actuation)-equipped 155cc, liquid-cooled single-cylinder engine now produces 18.4PS and 14.2Nm which is a dip of 0.2PS from the Yamaha R15 V3, though the torque has seen a slight bump of 0.1Nm. Now, while all this may not seem much, Yamaha says that the engine has been retuned to improve riding performance in the city.

Another big change with the Yamaha YZF-R15 V4 came in the form of the new bodywork, inspired by the new Yamaha R7. The new design, however, isn’t purely an aesthetic choice, as it has reduced the coefficient of aerodynamic drag (CdA) from 0.307 (on the the R15 V3) to 0.293. What does this translate to? Simply put, the lower the CdA, the better it is for the vehicle’s fuel consumption as well as its top speed. In fact, Yamaha claims the new bike has a higher top speed than the outgoing model.

It sounds interesting on paper, but can the dip in the performance of Yamaha R15 V4 really be felt in the real world? Well, we have tested the bike, so stay tuned to find out.
Yamaha R15 V4 User Reviews
- Neat condition bike with awesome road presenceThis bike is very good while daily riding is the main factor as the mileage is very good like 43 kmpl in city traffic and the maintenance cost is very low if you ride the bike properly. Also the road presence particularly of this edition is great. If you wish to look good while getting an optimum performance then you can definitely go for it. In my case this bike is in neat condition without any damages or missing parts. All the services done on time and so the warranty is valid.Read More1

- The Yamaha R15 V4 is a popular 155cc entry-levelI had a brother who likes riding this old r15 and I was small and didn't knew any super bikes at all, and this was my first super bike which had all sharpnes at edges, the colour, the speed, it had some personality. Its been amazing bike so far, smooth, light weight. Its top speed is pretty good. It gives good mileage. It is very nice for long rides. Performance of the bike is so good. Suspensions works very well on road. Yes, for sure but take my opinion and explore different bike, It may have something that this bike wouldn't have that charm but you can go for it, if you want sporty look and a good racing bike. Its nice.Read More6 1

- r15 V4 ReviewThe r15 v4 has the old punch while handling the BS6 engine with good aerodynamics and aggressive seating position. Its very easy to reach 140+ with default setting while it was not made for the long drive push, we can try the limits where I've driven around 25,000km in the same bike as well. I love it as my soul.Read More5 1
