There's nothing else out there like the KTM Duke. There wasn't when the original, mind-blowing 620 Duke came out in 1995, there isn't now the range has expanded to 125, 390 and 690cc versions. As a machine that's easy to ride yet with plenty of fun on offer, it has virtually no competition. Its limitations over distance or for either carrying luggage or a pillion, however, are clear to see. This one lacks little over the latest version in return for a sizeable saving, so is worth serious consideration.
