A factory-built dual-sport version of KTM's dirt-only 450 EXC, with street-legal lighting, DOT-approved turn signals, mirrors, horn and emissions equipment added. The review excerpt says it kept good trail performance, with softer suspension than a race bike and tall gearing, and it notes that the rear turn signal was prone to damage.
