What is engine power of Benelli 302R?

No, Duke 390 is a single cylinder bike, and benelli 302 is a dual cylinder bike. Hence, Duke 390 cannot match the loudness of Benelli.. neither with a stock exhaust or with any kind of aftermarket exhaust available in this world. Now for the others who have responded to Subhadeep. I am sorry but you cannot compare the sound of twin cylinder bike with a single cylinder bike. Benelli 302 comes with a dual cylinder engine whereas duke 390 comes with a single cylinder engine.. Changing the exhaust of your single cylinder bike will obviously change the sound of your bike but you can never match it to the the sound of a dual cylinder bike.

Dear Abhilashservice cost is on higher side in Benelli it's cost you 3 to 4k for first service after that 6k ....it's best for you go for AMC package which is cost effective. for more details contact the nearest dealership
