Segment: Naked / Road
Production years: 1996, 1997
In 1997, the Japanese motorcycle manufacturer launched the CB400SF Super Four, a standard motorcycle in its sixth year of production that received minor technical changes, such as updated carburetor air funnels, internal muffler structure, and Nissin brakes, which increased the overall weight by 1 kg (2,2 lbs).
The bike had its debut in 1991 at the Tokyo Motor Show and was powered by an updated CB-1 400cc engine, tilted backward for a more erect cylinder bank. The bike embodied the typical Universal Japanese Motorcycle (UJM) built in the 1970s but updated with modern technology.
For suspension, the bike packed a 41 mm telescopic fork on the front and a Pro-Link monoshock 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 with a dual-piston caliper on the rear wheel.
As for power, the 1997 Honda CB400SF Super Four took its thrust from a 399cc four-stroke four-cylinder liquid-cooled engine fed by four carburetors that helped deliver 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.
In addition, the bike came with standard features, such as a dual seat, an analog instrument cluster, lightweight cast aluminum wheels, a chromed exhaust system, a blacked-out steel frame, a round headlight, and a wide handlebar.
