2004 KTM 640 Duke II Yellow - Black

2004 KTM 640 Duke II Yellow - Black sits in the middle of KTM's single-cylinder supermoto lineup, a street-legal thumper built off the brand's enduro know-how rather than a clean-sheet road bike. This is a machine that rewards an aggressive, upright riding style — tight city streets, back-road corners, and the occasional dirt shortcut all suit it better than motorway slogs. The big single's torque comes on low and hits hard enough to loft the front wheel if you're careless with the throttle, and the chassis is light enough to flick between lines without much effort. Vibration and a firm seat remind you this is a dirt bike at heart, dressed up for pavement duty.

The 2004 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2003 example should focus on mileage, service history, and condition rather than spec differences.

Owners tend to be riders stepping away from conventional streetbikes who want something with more character and less polish — commuters bored with their Japanese fours, or supermoto converts drawn to the 2004 KTM 640 Duke II Yellow - Black's rawness rather than refinement.
