2006 KTM 640 LC4 Supermoto Black

2006 KTM 640 LC4 Supermoto Black sits at the aggressive end of KTM's single-cylinder lineup, built for riders who want dirt-bike reflexes on pavement. This is a big-bore thumper wearing supermoto wheels and sharp suspension, and it rides like it: tall, light, and eager to change direction, with a chassis that rewards aggressive braking into corners and a throttle hand that respects how abruptly that single-cylinder power comes on. It's not a comfortable highway machine, and it's not meant to be. Low-speed grunt and a narrow, flickable feel make it best suited to back roads, tight canyon work, and the occasional trackday rather than long-distance touring.

The 2006 model carried over without significant mechanical changes from the prior year — buyers comparing it to a 2005 example should focus on mileage, service history, and condition rather than spec differences.

Owners tend to be experienced riders coming from dirt or dual-sport backgrounds who want something raw and engaging rather than refined. Collector interest in the 2006 KTM 640 LC4 Supermoto Black remains moderate, driven mostly by riders who value its stripped-down, mechanical character over outright investment potential.
