KTM 640 Supermoto Motorcycle - Street (1999-2005)

The KTM 640 Supermoto, produced from 1999 to 2005, was a distinctive single-cylinder motorcycle known for its robust LC4 engine and supermoto styling. This model combined off-road agility with on-road performance, making it a popular choice for riders seeking a versatile and engaging experience. It featured a 625cc liquid-cooled, four-stroke, single-cylinder engine, typically delivering around 54-55 hp. The engine was paired with a Mikuni BST 40 carburetor and a five-speed manual transmission throughout its production run. While no distinct trim levels were offered, the 640 Supermoto received several updates. Early models (pre-2003) were noted for a less durable clutch bearing, suggesting improvements in later years. The 2005 model year brought a significant refresh, including revised bodywork, modifications to the camshaft and CDI, a split exhaust system, updated gearbox and air filter, a reworked seat and suspension components, and the addition of a second oil injector. These changes aimed to enhance performance and durability. Q: How do I know which parts fit my KTM 640 Supermoto?
