The all new ktm duke 390 mileage is not very good is giving. 20 to 30 I am using thes bike form 1 months and is gaining very bad performance. This bike is not comfortable like the old ktm duke 390 and is very bad to driving this bike. Reliability of this bike is not so much cool. The tyres of this bike making this bike just a jock the road grip is just a jock. Appeal is not very good. I suggest to be not buying this bike
