Its fuel-injected liquid-cooled SOHC four-stroke 450cc single-cylinder engine boasts an updated air intake sleeve and snorkel. On our in-house dyno, this mill pumps out 55.5 hp and 33.5 lb.-ft. of torque at the rear wheel.Jeff Allen

Clutch is stock, but Husqvarna adds a Rekluse cover to enhance the bike’s factory appearance.Jeff Allen
