KTM comes in 1999 with the new motorcycle 640 LC4 Supermoto. This KTM 640 has a liquid-cooled, SOHC, single cylinder. This engine is extreme reliable and powerful for this class. Providing it’s not still sitting on the dreadful Pirelli MT60 tyres it comes with the KTM 640 LC4 Supermoto handles sharply. The fully-adjustable WP suspension and four-piston Brembo brakes mean confident stopping is just a two-finger tug away.
