The new R15 S would definitely excel in its performance values. It will take less time than a version 2.0 R15 to reach 100 kmph as it gets a 2 kg reduction in its overall weight.
The mileage would also increase partially, making it good for an average fuel efficiency of 30-40 kmpl. The 12 litre fuel tank would make it good for a 450-500 km stretch on highways.
