2015 KTM 690 Duke ABS

The KTM 690 Duke is like a big supermotard, a type of bike that the Austrian manufacturer excels at producing. It delivers sharp performance thanks to a super-stiff and nimble chassis. You can have fun in the city as much as on the track, but those who don't possess the necessary skills or experience may find the 690 Duke too sporty for their own good. Its powerful and aggressive single-cylinder is one of the best production engines in the world, along with Aprilia's V4, BMW's inline 4-cylinder, and Ducati's V-twin.
