The KTM 250 Duke is a great option for those looking for performance and convenience. It has a 248.8 cc engine that generates 30 PS @ 9000 rpm and a torque of 24 Nm @ 7500 rpm. The price tag of Rs. 2,28,851 is a great deal for what you get. 

On the other hand, the Bajaj Dominar 250 is a great sports tourer and is fit to purpose. It has a 250cc motor that works beautifully with the comfortable touring ergonomics. The price tag of Rs. 1,66,355 makes it a great entry-level option. Ultimately, the choice depends on your budget and preference. We would suggest you to take a test ride of both the bikes before making a final decision.
