                  One of the best performances sports bike with great mileage in city around 24 and on highway 30 which is good according to a sports bike with this much performance, writing style is also very comfortable, not to aggressive and the bike, very easy to manuver. I think you should go for this bike if you are looking for great performance with efficient mileage and comfort riding style.

                  Review of my duke 390
                  My purchase of the bike was the best thing ever. It was always my dream to buy a 390 and the performance is the best in its class. The maintenance is very cheap, mileage is decent according to this engine. Overall, its the best bike in its segment. Beast for a reason. Comfort and performance is on next level.

                  Its a great bike for beginners. The quick shifter, cruise control feature and the throttle response makes the ride really smooth. My experience with bike has been amazing and even on long rides the ride is comfortable. There is nothing more to say about it, you just have to experience it. At this price range, I don't think you will find a bike with these many features.

                  The beast on the loose 9k driven only KTM Duke 390
                  Most aggressive 398 cc powerful bike only driven 9000 km in less than 2 yrs. It delivers a surgical riding experience with a punchy engine that surprisingly settles into great fuel economy on long highway scratches. It just got minor scratches on tank pad else its mechanically mint. If you want raw power then this is for you.

                  Riding experience is too good, this bike is futuristic at this price range. looks are awesome 398 cc, this bike can handle turns very well, maintenance period is too long 30 kmpl good range as an 400 cc bike. Very well designed, engine performance is too good into 3.5 lakhs segment good option to buy.
