Q. Duke 200 mileage is 35 kmpl and duke 390 mileage is 21 kmpl. But i can't understand that why duke 250 mileage is 41 kmpl i.e comparatively duke 250 is better. And yes i want to know the reason behind the low mileage of duke 200 and duke 390?

Bro my name is yesh and my friend has duke 200 and another friend has 250 bs6 both bike are powerful but 250 is more powerful but it is giving. 38 to 40 kmpl but the duke 200 is giving same or sometimes less milage this is because the 250 engine is more refined then the 200 and power and torque has good combination this the reason it gives good milage about 390 it is high recing motorcycle so it will give 28 to 30 in city and 30 to 35 on highway because I used to go Sunday rides with my friend because I own the duke 390 bs6

It all depends upon how you ride, I used to own a duke 200 and the mileage I got was 47Kmpl on a highway and in city it used to touch close to 39 and 40. I am a single user of the bike and I use to take good care of my bike. but overall it varies because lot of factors come in.

Am duke 390 owner, mileage of mine is approximately 30 during long rides n in city it's 18-20. N coming to duke 200 mileage is very good. In long rides it will reach nearly 50.. Duke 250 is almost same as 200. In city 200 wl give 35+ but not 250
