That said, the exploit we’ll be examining today hails from a different manufacturer. The company in question is none other than Norton, and the bike you see here was once an undistinguished 1974 Commando 850—before this ambitious crew got their hands on it, that is. Within its double-cradle frame, the donor carries an air-cooled parallel-twin powerplant that boasts a healthy displacement of 828cc. At about 6,200 rpm, this bad boy can produce up to 60 horsepower, along with 48 pound-feet (65 Nm) of torque output at 5,000 revs. A four-speed transmission channels the engine’s force to the rear wheel via a chain final drive, leading to a top speed of 118 mph (189 kph).
