Two decades ago, the original Duke was nothing short of revolutionary. KTM’s first single-cylinder street bike grew into a cult classic, adding extreme fun to a raw and radical concept. In 2017, the fully revised 690 DUKE stays faithful to its ancestor’s ways, but adds future-proof refinements: impressive smoothness, sophisticated electronics, improved ergonomics and a good old power boost over last year’s model. This firmly cements the world’s strongest single-cylinder production motorcycle at the cutting edge of engineering. Speaking of which: carving corners has never been more fun, thanks to its revised fork offset. Long live the Duke!

• Engine: The brilliant LC4 showcases twenty-four carats of fun. From the trademark 690 cm³ thumper, the engineers have now extracted a whopping 73 hp (54 kW) and 74 Nm of torque, making light work of the equally lightweight 690 Duke. How it happened? They completely reworked the cylinder head, inserted a new, ultra light and extremely strong piston and connection rod, rerouted the air intake through a resonator chamber and provided the crankshaft with sleeve bearings. As a result, the powerband is a thousand rpm wider, which means an even more uniform power delivery, especially in the mid to high rev range. Twin ignition featuring plug-selective mapping, rock solid but featherweight internals and optimized intake and exhaust systems cultivate this massive mono to be as strong as it is smooth, assisted by an advanced ride-by-wire system, which guarantees great refinement as well as low fuel consumption and emission figures. You’re green, while they’re green with envy. And you haven’t even begun mentioning upmarket goodies like a standard slipper clutch.
• Cylinder head: Inside the cylinder head, the exhaust valves are actuated by roller rockers while the camshaft powers the intake valves. Therefore, the valve timings can be controlled with far greater accuracy. The result is more peak power over a broader rev range. Win-win!
