The Honda CB400 Super Four was a standard motorcycle part of the CB series manufactured by the Japanese maker since 1992 at the Kumamoto plant, which embodied the typical 1960s Universal Japanese Motorcycle (UJM) but with a touch of modern technology.
The motorcycle was first introduced in 1991 at the 29th Tokyo Motor Show as a 400cc version of the CB1000 Super Four and launched in 1992 in Japan with an engine similar to that used by the early CB-1 machine.
In 2006, Honda launched the CB400SF Super Four, a motorcycle that came with standard features, such as a black-finished exhaust system with a chromed muffler, a round headlight with a chromed ring, a dual seat with a passenger grab handle, die-cast aluminum wheels, and an analog and digital instrument cluster.
The bike came with a high-tension steel cradle frame that packed a telescopic fork on the front and a single shock absorber on the rear, coupled to a set of three-spoke aluminum wheels fitted with two 296 mm discs with four-piston calipers on the front and one 240 mm disc with a dual-piston caliper on the rear wheel, which provided strong braking performance.
In the power department, the 2006 Honda CB400SF Super Four had its soul brought to life by a 399cc four-stroke four-cylinder liquid-cooled engine fed by a PGM-FI fuel injection system that helped deliver an output power of 53 hp with maximum strength at 11,000 rpm and 40 Nm (30 lb-ft) of torque available at 7,500 rpm.
