MILEAGE- KTM RC 390 is not the bike to be preferred if mileage is you main concern. It hardly gives a mileage of 20-25 kmpl.
COMFORT- It cannot be used for long rides. You will definetely get a back pain and the back seat is also not that comfortable. After a month of purchasing a started to get back pain. It is not at all comfortable.
RELIABILITY- You can test its speed. Throttle down the road. It’s great at speed but has a poor handling. Make aure you don’t lose your balance. In recent news I saw most of the bike accidents with KTM RC.
ROAD GRIP- As I said earlier it has a great speed but a poor handling. You tend to slip most of the time.
APPEAL- The only thing I like most in this bike is its looks and the two stars I gave is for its looks and a little for its speed. It has all the looks ans appeals of a superbike. It looks are amazing though one should not judge a book by its cover.
