2009 KTM 690 Duke

The exotic outsider just a few years ago, the Duke has long since created its own domain, including its own values. Or better said: performance values. If superathletes feared the Duke then, now it’s practically unbeatable.

To ride the Duke you need skill, courage and of course: style!
