Supermotos are easy to fling about thanks to wide bars, lightweight, sticky tires and a surplus of braking potential. And the Duke is not exception. Point it at a damp trackday and you won’t find a faster bike through the corners. The front Brembo is sensitive and strong, the riding position perfect for both attack mode and pottering and the seat’s almost comfortable. Almost.
The thumping carb-fed SOHC single is all about delivering maximum power at minimum revs, with peak torque at just 5000rpm. This means there’s instant shove and a healthy mid-range, which combined with a dry weight of 152kg means easy wheelies. There are some vibes, yes, but they’re not intrusive and really only add character. The five-speed gearbox is so good you’ll forget it’s there.
The Duke is solidly reliable; well screwed together and well finished. There’s no single cylinder motor that’s as durable as a four, though, and anything with more than 25,000 miles on the clock may well be an expensive rebuild waiting to happen. Keep it well away from winter salt or it’ll corrode like hell.
Dukes are expensive, but they do hold their value well and owners tend not to put huge miles on them, making them a decent used buy. Find a KTM 620 Duke for sale.
