Upgrade to a higher top speed of your bike using this KTM Supersprox 40T which is 2 teeth lower than the stock rear sprocket size that is that 42. There are many sizes available that is 39, 38 and 37. Using smaller size rear sprocket will increase the top speed, but at the same time decrease the pick-up of your Duke 200. For your information, the stock sprocket size for KTM Duke 200 is 14T front and 42T rear.
Changing the sprocket is the easiest way to increase the top speed of your bike without modifying your engine. This modification will change the characteristic of the Duke 200 but will you can adapt to it after few minutes riding it.
I think the change to smaller size for the rear is something that the Duke 200 should do since there is so much power from the lightweight bike of 129kg that churns out 25hp. 15-37T might be a good size to test. Anyone dare to do it?
There is also this steel KTM sprocket for better reliability with the size of 37T for that higher top end. But there are some people says that the is an electronic speed cut off that limits the top speed to only 140km/h. Is this true?
