The 690 Supermoto was the street-oriented supermoto version of KTM's new LC4 single, sold in 2007 and 2008. It had fuel injection and an electronic throttle, a light APTC clutch and Brembo brakes on a trellis frame. Reviewers found the engine much smoother than earlier LC4 units and the bike best suited to fun, street-focused riding rather than racing.
