2005
The 2005 KTM 640 LC4 Adventure represents a specific point in KTM's history of producing capable, single-cylinder adventure motorcycles. Building upon the legacy of the LC4 engine, this model year aimed to provide riders with a machine ready for long-distance travel and challenging terrain. It directly competed with bikes like the BMW F650GS Dakar, offering a different approach to adventure riding with its focus on off-road prowess.
At the heart of the 640 LC4 Adventure is a 625.0 ccm single-cylinder, four-stroke engine. This powerplant is capable of producing 53.6 HP (39.2 kW) at 7000 RPM, providing ample power for tackling diverse environments. The engine generates a torque of 55.0 Nm (5.6 kgf-m or 40.6 ft.lbs) at 5500 RPM, allowing for strong acceleration and confident climbing ability. The motorcycle has a dry weight of 158.0 kg (348.3 pounds) which helps it to be nimble on off-road trails. The fuel capacity is 25.50 litres (6.74 US gallons) which gives it a good range between fill ups.
The riding position on the 640 LC4 Adventure is upright and commanding, designed for long days in the saddle. The high seat height of 945 mm (37.2 inches) provides excellent visibility, although it may present a challenge for shorter riders. The suspension is designed to absorb bumps and ruts, making it suitable for unpaved roads and trails. While not the most comfortable motorcycle for extended highway cruising, it excels in environments where its off-road capabilities can be utilized.
The KTM 640 LC4 Adventure 2005 is primarily aimed at experienced riders seeking a rugged and dependable machine for adventure touring and off-road exploration. It's a motorcycle for those who prioritize function over outright comfort and are willing to trade some refinement for capability. It is a competent choice for those seeking a single cylinder adventure bike with a strong off-road pedigree.
