The brand new and completely re-vamped KTM 690 DUKE R with even more power, even more valuable components, an even more engaging chassis and even more sophisticated riding assistance.
The standard 690 Duke is a firecracker of a bike, light as a feather and lightning quick. But we wouldn’t be true to ourselves if we didn’t try to push things just a little bit further. So we did, creating the ultimate single-cylinder street bike on the face of the planet. Really, it’s that spectacul’R.
The latest LC4 showcases twenty-four carats of fun. With this gem of an engine now breathing more freely thanks to the standard Akrapovič slip-on exhaust, the engineers have managed to extract a whopping 75 hp (55kw) from the trademark 690 cm³ single thumper; unseen in the monocylinder motorcycle world. 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 improved crankshaft with new sleeve bearings. As a result, the powerband could also be made 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.
Inside the new cylinder head, roller rockers actuate the exhaust valves while the camshaft powers the intake valves. Therefore, the ignition timings can be controlled with far greater accuracy. The result is more peak power over a broader rev range. Win-win!
In a free-revving engine like this, you want to smooth things out a bit. That’s why the camshaft serves as a bonus balancer shaft, nipping annoying vibrations in the bud.
The electronic engine management system lives to make the LC4 shine. Twin ignition with individual mappings for each spark plug ensures that your precious fuel is always burned to perfection, irrespective of load and engine speed. And then there is genuine ride-by-wire, in other words: electronically controlled throttle valve actuation without any mechanical linkage.
A restricted power version is available for those riders who have just started their two-wheeled career. But restricted power doesn´t necessary means restricted fun: thanks to its lightweight and dynamic chassis, the KTM 690 Duke R is the perfect playmate for all ages. Regardless of your experience level, de 690 Duke is your license to thrill.
