Here are the spy shots of the 2017 KTM 390 Duke test mule under heavy camouflage spotted somewhere in Pune, which reveal visual changes including a reshaped fuel tank and side panels, an updated seat unit and a revised rear light.
The new front light appears to be a new LED unit that works with the updated side panels for a new and slightly more aggressive look.
The Duke 390 now gets a revised exhaust system. This makes us to speculate that the motorcycle is expected to get host of engine updates to satisfy new Euro regulations.
The 373cc single-cylinder motor currently produces 43bhp and this may well go up slightly because of changes made for the new regulations. The results will be more stable combustion, more power but also increase fuel economy. The powertrain will benefit from updated engine management systems, ride-by-wire tech and slipper clutch.
There is also the possibility that KTM will have fitted a second balancer shaft in the cylinder head, as first seen on the firm’s 690 Duke launched at the end of 2015. This extra balancer shaft works to smooth out the low rpm engine response, giving near twin-like smoothness from a single cylinder.
