About this model
About the Ktm 640
The KTM 640 LC4 is a 625 cc (marketed as 640) four-stroke single-cylinder engine available in several variants: Adventure, Duke II, LC4 Enduro, and LC4 Supermoto. The LC4 engine is known for its strong low-to-mid-range torque and robust construction. KTM built the 640 family from 1999 to 2007. Water-cooled, it produces around 54 hp.
The KTM 640 targets riders looking for a light, versatile single for both road and off-road (Adventure/Enduro) or sporty road use (Duke II/Supermoto). Its low weight (around 150 kg) and high engine mounting make each variant more agile than most competitors. Rivals include the Honda XR650R and BMW F650GS. The single-cylinder vibration takes getting used to on long highway stretches.

Before you buy
What to check before buying
- Check valve and seat condition carefully; the LC4 640 requires regular valve adjustment (every 6,000–10,000 km).
- Inspect oil consumption; the LC4 engine is known for minor oil burning on older or poorly maintained examples.
- Check the balance shaft gears inside the engine; chain slop causes noise and accelerated wear.
- Inspect the exhaust and heat shield for cracks and rust; the high-output single runs hot and exhaust ageing is rapid.
