Q. Which bick is best FZ 2.0 and MT-15?

MT 15 is a 155 cc bike which has a Racer genetics in it. So, it produces more torque and power (similar to R15)But with that, it will also give lesser mileage.So, if you need a smooth no non-sence bike which is good with mileage, go for FZ.Else if you like initial torque and want to cross 100 kph quite often, go for MT15

Depends on what you want and your budget. If you want good mileage then go for the FZ. If you want a bit extra in power and performance then go for the MT. Personally I would recommend the MT.

MT 15 because it is 155.1 CC with 6 gear and an informative console with Single Channel ABS.
