Buddy anything is possible in this world. we can have 180 size tyre on 200 NS if we want
just saying.. 
there are people who go to extreme levels
he would have cut the plastic so that it gives space for exhaust pipe.As i already mentioned it could be direct fit since the bottom of Duke and NS are same but exhaust pipe is the one standing between

I tried to google but no use. can you search some clear pictures of people using KTM hand guard and engine guard on NS and post here?
It would give some idea for people. If its possible even i am interested to buy those accessories.
India is the place where NS is manufactured and most NS are running here only but we dont have any accessories apart from center stand

See this link http://cxrider.com/2013/03/16/firepa...-doyan-turing/ or search google with 200 NS fireparts.
other small countries with lesser number NS running there, having so many after market accessories.
