The Honda CB400SF Super Four was a standard motorcycle part of the CB series in Honda's range, powered by an updated version of the engine used in the CB-1 machine, with the looks of the typical Universal Japanese Motorcycle (UJM) manufactured in the 1970s.
In 2005, the Japanese motorcycle manufacturer launched the CB400SF Super Four, which brought along some improvements, such as the addition of an analog preload adjustment mechanism for the front suspension and a high-density polyurethane material for the seat.
In addition, the 2005 model came with standard features, such as a blacked-out exhaust system with a chromed muffler, a round headlight with a chromed ring, a dual seat with a passenger grab handle, three-spoke cast aluminum wheels, and a digital and analog instrument cluster.
For suspension, the bike packed a 41 mm telescopic fork on the front and a Pro-Link shock absorber on the rear, while the braking power was handled by two 296 mm discs with four-piston calipers on the front wheel and a 240 mm disc squeezed by a dual-piston caliper on the rear wheel.
In the power department, the 2005 Honda CB400SF Super Four had its soul brought to life by a 399 cc four-stroke four-cylinder liquid-cooled engine that delivered an output power of 53 hp with maximum strength at 10,000 rpm and 40 Nm (30 lb-ft) of torque available at 7,500 rpm.
