Vehicle Information
KTM 620 Duke Motorcycle - Street (1994-1998)
The KTM 620 Duke, produced from 1994 to 1998, was a pioneering supermoto and KTM's first street motorcycle. It was powered by a liquid-cooled, single-cylinder, SOHC, 4-valve LC4 engine.
The initial "Duke I" generation (1994-1997) featured a 609 cc engine, delivering approximately 55 hp. A notable update within this period was the introduction of an electric starter in 1996, replacing the earlier kick-start only models. For 1998, the model transitioned to the "Duke II" generation, which saw an engine displacement increase to 625 cc, though it was still commonly referred to as the 620 Duke. This Duke II engine produced around 50 hp. While primarily offered as a single model, some year-specific designations like "Duke E" or "GS 620 Duke" appeared, alongside varying color schemes. FAQ:
