Which one is better - Pulsar NS200 or Pulsar RS200 or KTM 200 Duke?

I have ridden all the three i think Duke is the winner i suggest you to ride the bikes and check for yourself

From the performance and comfort factor, the KTM 200 Duke is a winner for sure. With its lightweight chassis and engine, it is the quickest one from all the above bikes. When it comes to design, the RS200 is a faired bike, looking much larger than both the others and having the best styling in the best possible price. The 200 NS comes with an attractive price tag of INR 91,500 which makes it the cheapest performer out of both. If you like street bikes and want some pocket friendly performance, Pulsar 200 NS is the best option as it can be a fair deal. Spending INR 30,000 will get you some extra fairing and other performance and style parts like projector headlamp, fuel injection etc. Choose wisely.
