2015 KTM 690 Duke and 690 Duke R

2015 KTM 690 Duke and 690 Duke R

Next up from the 2015 KTM Naked Bike Media Launch are the mid sized Dukes, the 690 Duke and 690 R. We had a 690 Duke for a long term test on derestricted a couple of years ago and it’s a bomb proof, really fun nimble bike. The engine sounds pretty dull with the stock pipe, but really picks up at high RPM’s with an opened up Acrapovic on there. Check out the review here if you like.

    this bike is underpowered for highway riding, the engine is f&*n usless below 3000Rpm! it cuts out for no reason some times at the lights the breaks are great

      What do you expect from a 1 cilinder? No way it’s under powered with that weight. It’s faster than any sportscar.
