Mostly, costly and high end Xtreme sports bikes are considered to have more cubic-capacity (cc / displacement), and therefore are assumed to give less mileage ! That means these bikes need an initial huge amount of money and then further bucks are spent for its fuel requirements...
Now here's a bike from Yamaha India, which has all the looks of a sports bike while having the cubic-capacity equal to that of Pulsar (150cc).
One of the main attractive feature of this new bike from "R" series, are the under cowls that are based on the image of a diffuser, to give them the best form for aero-management. These are not cowls for simply enclosing the engine, but forms composed of blade surfaces that actively control airflow.
The YZF-R15 is the first India-made motorcycle in this class to mount a liquid cooling system for higher engine performance. Liquid cooling has not been use on 100 to 225cc class motorcycles in the past.
The YZF-R15 has a 6-speed transmission too. Even if you have a high-performance engine, the power development is going to be different in the different rpm ranges. The reason for a 6-speed transmission is to be able to make the most of the engine╩╝s power at any point in the rpm range.
According to Yamaha:
The designs were developed in the same modeling room where YZF-R1 designers worked. Information was shared, ensuring that the R lineage would be transmitted.
