The KTM Duke 690 is a bike that has a reputation for being a versatile platform to work from as far as customizing goes, with owners often taking their bikes and making them their own. As a result, we’ve seen a vast array of modifications, from down and dirty performance upgrades to more outlandish cosmetic alterations.
