Q. I have doubt regarding the ground clearance whether it will hit the illegal speedbreaker or not... and does it have more ground clearance than royal Enfield classic 350?

Royal Enfield Classic 350 offers a ground clearance of 135 mm, while that of KTM 250 Duke is 185 mm. Clearing those meanie speed breakers would not be a issue here, however, you will have to careful while manoeuvring because of the engine cowl. For a better understanding of compatibility and riding comfort, we would suggest you to take a test ride. Follow the link and select your desired city for dealership details.
