In 150 cc segment, other bike makers have their own technologies and the major one competing Yamaha are the Bajaj's DTS-i and Honda's HET. We cannot say which one is the best out of all as they are not explained properly by their respective owners. You will find a list of features like increased mileage and refined performance when you will compare them. This is because all of them are targeted at the above listed points. Honda Eco Technology makes the CB Unicorn more powerful and fuel efficient whereas the Bajaj Pulsar DTS-i technology makes them the acceleration king of the segment. Blue core has refined all the Yamaha engines ranging from scooters to the motorcycle, which is the only reason that claimed mileage of FZ has increased from the one sold few years back.
