About this model
About the Ktm 620 Duke
The KTM 620 Duke (also known as the Duke II) is a compact, lightweight naked bike powered by the KTM LC4 609cc single-cylinder four-stroke engine. Produced from 1994 to 2000, it succeeded the original KTM 400 Duke. With approximately 48 hp and a ready-to-ride weight of just 149 kg, the 620 Duke was one of the sharpest and most agile motorcycles in its class. The steel-and-aluminium frame, combined with WP suspension front and rear, delivered riding dynamics that few rivals could match at the time.
The KTM 620 Duke targets experienced riders looking for a compact, direct naked bike for urban use and twisty country roads. The single-cylinder delivers its power aggressively in the upper rev range, making it less suitable for beginners. Long-distance riding is uncomfortable due to the small tank and sporty seat. Competitors included the Husqvarna Super Moto 610 and the Honda NX650 Dominator. Today the 620 Duke is a sought-after classic with a devoted following.

Before you buy
What to check before buying
- Check oil pressure and valve clearances on the LC4 single: camshaft wear is a known issue on high-mileage examples.
- Inspect the cooling system for leaking hoses and a functioning thermostat; there is no air-cooled variant in the 620.
- Look for rust on the exhaust pipe and silencer: original pipes corrode quickly without protective coating.
- Check the WP forks for damaged oil seals and dented stanchions.
- Ask about clutch maintenance: the dry clutch on the LC4 needs periodic adjustment and wears in stop-start traffic.
