Look of the Yamaha R15 2.0 is very nice but the main problem is from cost and the Mileage. Price of the Yamaha R15 2.0 is very high while comparing with R15. It is an high budget to the normal citizens those who can not afford that much money to invest.
Second problem from the Yamaha R15 2.0 is Mileage Problem. It is giving very low Mileage. It was the main drawback for the Yamaha R15 2.0. Even though it is an Sports Bike but the engine sound is coming loudly. It sounds like spammy.
The model of gear system is not good. it was best in R15 only. they changed little bit system near the Main engine of the vehicle.
