2007 KTM 640 LC4 Supermoto

2007 KTM 640 LC4 Supermoto sits in the middle of KTM's single-cylinder LC4 family, above the smaller SMC and below the brand's V-twin supermoto offerings. This is a tall, lean, slightly unhinged street bike built around a thumping big single that rewards riders who want to feel the engine working rather than hiding behind smooth multi-cylinder refinement. It's happiest flicking between tight corners, standing hard on the front brake into roundabouts, or being tossed sideways on loose pavement — the kind of bike that makes a commute feel like an event. Ownership means accepting some vibration and a firm seat in exchange for a chassis that genuinely wants to be hustled.

The 2007 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2006 example should focus on mileage, service history, and condition rather than spec differences.

Typical buyers are experienced riders stepping down from bigger sport bikes or up from smaller supermotos, often with dirt riding backgrounds who want a street-legal machine with attitude. Collector interest remains moderate, mostly from LC4 loyalists who appreciate the model's raw, unfiltered character.
