2004
The 2004 KTM 640 LC4 SM Supermoto represents a significant year for the Austrian manufacturer's entry into the supermoto category. Building upon the LC4 engine platform, this model aimed to offer a raw and engaging riding experience. It faced direct competition from models such as the Suzuki DR-Z400SM, which offered a similar blend of street usability and track-inspired handling. The 640 LC4 SM sought to carve its own niche with its distinctive KTM character and potent single-cylinder engine.
At the heart of the 2004 KTM 640 LC4 SM lies a 625.0 ccm single-cylinder, four-stroke engine. This powerplant produces a maximum power output of 53.6 HP (39.2 kW) at 7000 RPM. The torque figure is equally impressive, peaking at 55.0 Nm (5.6 kgf-m or 40.6 ft.lbs) at 5500 RPM. All this power is delivered to the rear wheel, contributing to its punchy acceleration and ability to loft the front wheel with ease. The motorcycle's dry weight is 149.0 kg, which contributes to its agile handling characteristics. Fuel capacity is 12.00 litres, allowing for decent range between fill-ups.
The riding experience on the 640 LC4 SM is characterized by its upright riding position and responsive handling. The seat height is a tall 910 mm, which might be challenging for shorter riders but provides excellent visibility. The suspension is firm and well-damped, offering good feedback from the road. The bike's responsiveness makes it feel light and easily flickable. However, it is a single-cylinder motorcycle and not designed for long trips, which means the comfort is limited.
The KTM 640 LC4 SM is aimed at riders who appreciate a raw, unfiltered supermoto experience. It's ideal for those who enjoy carving up twisty roads or hitting the occasional track day. It prioritizes performance and agility over long-distance comfort. It is best suited for experienced riders who are comfortable with the demands of a high-performance single-cylinder motorcycle. If you are looking for a supermoto with character, the 2004 KTM 640 LC4 SM is a worthy contender.
