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. The seat is narrow to let you climb over the bike for faster cornering, but you’ll be thankful for the small tank and the chance to get off after just 70-odd miles.
This KTM 640 LC4 Supermoto's liquid-cooled, SOHC single-cylinder motor has been in KTMs for over a decade, and in the 640 it’s definitely as its most civilised. But if you’re new to the world of supermoto you’ll probably think it rough and vibey. They’re all like that, Sir. Unlike the spunkier SMC range, which flat-slide carbs, the 640 gets a 40mm CV item for a more user-friendly response, especially around town.
The KTM 640 LC4 motor is extremely reliable, providing it’s serviced regularly. Every 3000 miles there are two oil filters to change, but that’s a 30-minute job. Change the oil, too – that takes about another 20 minutes, but those chores will keep the motor perkier for much longer. Adjusting the valve clearances is easy thanks to a simple screw and nut arrangement. Keep the 640 away from salted roads – or else it corrodes like hell.
The KTM 640 LC4 Supermoto is very good to buy, rubbish to sell. Supermotos are a poor monetary investment. Find a KTM 640 Supermoto for sale.
