The tracker-inspired Svartpilen is powered by a dual-counterbalanced 692.7cc single tucked tightly within a steel tubular trellis frame. This 75-hp, KTM-developed LC4 engine is used in a bevy of machines including the 701 Supermoto, and 701 Enduro. It also finds a home in the KTM 690 Enduro R and 690 SMC R. and it's with good reason; no other single-cylinder thumper delivers tire-twisting torque (a claimed 53 pound-feet) like the LC4. It's truly a legendary powerplant that is smoother than it should be considering its raucous delivery. Many a twin could only hope to have as much character.
