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
- Yamaha r15 v4 is a great fully faired sports bikeThe reason i chose this bike was quite a story in short, i was a student who was about get in college and i needed a bike to travel a quite moderate distance. When i was searching for a bike which is highly affordable as well as stylish on the looks and has great features too! Then i came across this masterpiece which was totally worth it. The ride is great so far. But there are few factors to look for if a beginner is going to buy this bike, as a fully fair bike the biggest issue would be comfort on long ride eg. Posture issue because of the aggressive stance fully fair bikes usually have. But for the short to moderate distance its great soo far. And handling also good, and mileage is better than expected. One more thing to consider, if someone lives in a crowded city like area they can this as this bike isn't a street fighter or naked body bike for city specific conditions. I would absolutely recommend this bike to even a beginner who want to get a thrilling ride experience of a fully fair bike at price rang as low as this, mileage also great compared to other similar bikes, great handling too, maintenance is also fairly rated i would say, totally worth it!Read More2 1
