The Husqvarna 701 Supermoto is powered by KTM’s mighty 690cc liquid-cooled SOHC 4-valve engine, the most powerful single in production today. It delivers a claimed 69 horsepower at 7,000 rpm and 49.5 pound-feet of torque at 6, 500 rpm. This powerplant features a 102mm bore and a 84.5mm stroke, together with 40mm inlet and 34mm exhaust valves. The twin-sparkplug ignition system has staggered timing to obtain the most efficient combustion, and the engine breathes through a 46mm Keihin throttle body. What’s more, the ride-by-wire throttle has three response modes: Soft, Standard, and Advanced.
