KTM 690 Duke R (2011)

The KTM 690 Duke R is a masterclass in stripped-back, high-performance design. Its 690cc, 70bhp single-cylinder engine delivers its power in a characteristic burst, making it perfect for exiting tight corners with precision and flair.

With its lightweight construction of just 148.5kg/327lbs (dry), the Duke R is a handling dynamo, its WP suspension – now with slightly firmer spring rates – working in harmony with its slick six-speed gearbox to create a riding experience that’s both exhilarating and intuitive.

As you carve through the twisties, the Duke R’s orange frame and blacked-out components seem to blur into the distance, leaving only the thrill of the ride. And with its razor-sharp handling and willingness to entertain, this pint-sized powerhouse is sure to leave even the most seasoned riders grinning from ear to ear. It’s a truly unforgettable experience that will leave you craving more.
