I have brought ktm bike about months ago , I have purchased it for it looks colour attracts me. The bike is good for the similar type of bikes available in market . I only hate of sound it generates when it starts . Otherwise I like the bike.
Mileage - for my bike it gives about 30 kmpl of milage which is I thought good enough.
Comfort- comfortable bike for biker as well as for the back seater . Nice seats arrangements - Looks cool.
Reliability - the ktm product gives totally reliable properties . As I have seen the bike gives same milage as I had told before . Headlight front and back pretty awesome.
Road grip - talking about the tyres the bike has well shaped tyres . In all ktm bikes kt-390 has good tyres . This tyres are so good that they allow to more bend down while turning and gives confidance to bend more . This bike has one disadvantage that the tyre worns out too fast . And I have seen that cost of tyres are 10% cost of bike. So look over it.
- buy the bike if interested gives preety good results
