KTM has unveiled few details and images of the 2016 690 Duke prototype. For 2016, the Company confirmed that its single-cylinder naked bike will get some significant updates to bring about more power and refinement, with less vibrations.
KTM has revised the Duke’s LC4 Single engine by increasing the bore from 102 mm to 105 mm but shortening the stroke from 84.5 mm to 80 mm. As a result, the total displacement now is 693cc, 3cc higher compared to the old one with 690cc. Furthermore, the rev limit has been increased by 1000 rpmand there is a second balance shaft has been added to reduce vibrations. The bike also gets a more compact cylinder head. The new engine is claimed to deliver 7% more power and a 6% more torque over its predecessor while smoothing out power delivery at low rpms. Three riding modes – Street, Sport, and Rain – are selectable by the updated left handlebar switchgear.
A Bosch 9M+ switchable ABS will be standard but traction control will come as an optional package. A new TFT display replaces the semi-analogue unit that found on the current model. The 2016 KTM 690 Duke has the same frame as the current model, but a revised triple clamp offset to improve handling. The seat is new.
The R-badged version of the 2016 KTM 690 Duke will have all of the standard model’s features and adds an Akrapovic exhaust, adjustable front and rear suspensions, higher-performance brakes, as well as more electronics.
The KTM 2016 690 Duke will be offered in two colors, black and a second color scheme which to be revealed at this year’s EICMA motor show.
