In 1993, the Japanese motorcycle manufacturer launched the CB400SF Super Four, a standard motorcycle part of the CB series in its second production year that didn't receive any changes whatsoever.
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.
Also, the carburetors were changed from down-draft to side-draft type, a more conventional chain drive system was used instead of the gear cam drive system that set the redline at 12,500 rpm, and wider gear ratios that defined the versatility of the bike.
As for power, the 1993 Honda CB400SF Super Four took its muscles 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.
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.
In addition, the bike came with standard features, such as black-finished cast aluminum wheels, a dual seat, a chromed exhaust system, an analog instrument panel, a blacked-out steel frame, and a round headlight.
