The KTM 640 LC4 Enduro is a testament to the brand’s dedication to creating versatile and thrilling motorcycles. Powered by a four-stroke, single-cylinder engine with SOHC and 4 valves, this bike boasts a unique blend of on-road and off-road capabilities. With a history dating back to 1987, the LC4 has undergone numerous refinements, including the addition of electric start, counterbalancers, and a high-flow head.
The bike’s appearance is deceptively understated, with styling cues reminiscent of modern dirt bikes. However, once astride, the 640’s considerable weight and unique ergonomics become apparent. The engine’s exhaust note is unexpectedly muted, but its notorious vibration is still a characteristic of this bike. As the bike has broken in, the vibration has become less pronounced, and I’ve grown accustomed to its presence.
On the open road, the LC4 Enduro is smooth and comfortable up to 120 km/h, but the combination of wind and vibration becomes more pronounced at higher speeds. But it’s when the curves come into view that the fun truly begins, as the bike’s handling and agility reveal themselves. With its unique blend of on-road and off-road prowess, the KTM 640 LC4 Enduro is a must-ride experience for any adventure-seeking motorcyclist.
