About this model
About the Ktm 640 SM
The KTM 640 SM translates the LC4 enduro platform into a road-focused supermoto. Its 625 cc single delivers immediate thrust, while 17-inch wheels, substantial WP suspension and strong brakes provide quick steering and abundant feedback. It is a raw, tall and light motorcycle that favours tight bends and urban rides over sustained motorway comfort.
The large LC4 single vibrates noticeably and demands documented maintenance. Check oil and filter changes, valve clearances, rocker rollers and the water pump. Many examples have been modified or ridden hard, so inspect wheels, brakes, steering head and subframe closely. The specifications cover the mid-2000s 625 cc 640 SM generation. No exact, safely licensed image was proposed, so an incorrect KTM photograph is deliberately not added.

Before you buy
What to check before buying
- Check evidence of frequent oil and filter changes and valve-clearance service; the LC4 responds poorly to neglect.
- Listen to the rocker rollers and valve train and inspect magnetic drain plugs for unusual metallic debris.
- Inspect the water pump, seal and cooling circuit for leakage, oil-water contamination or overheating traces.
- Test the starter, freewheel and battery both cold and hot; kickback and reluctant starting can reveal wear.
- Check the 17-inch rims, brake discs, steering-head bearings and subframe for stunt, crash or hard track-use damage.
