HONDA CB400SF Super Four (2003-2004) Specs, Performance & Photos

In 2004, the Japanese motorcycle manufacturer launched the CB400SF Super Four, a standard motorcycle made at the Kumamoto plant that embodied the typical 1970s Universal Japanese Motorcycle (UJM) updated with modern technology.

The 2004 model featured several updates that included once again, changes to the VTEC system, which was set to trigger at 6,750 rpm in sixth gear and, at 6,300 rpm in gears one to five, along with other updates to the ignition timing map.

The bike also came with more glass wool in the exhaust pipe collector that reduced noise to 72 dB, a new lower seat with a single grab rail instead of the surface belt, a lightweight rear caliper, and an updated front suspension that improved the ergonomics.

In addition, a multi-reflector headlight, LED taillights, a new fuel tank, and a rear cowl offered improved safety and styling, while the overall weight was increased by one kg (2.2 lbs).

The bike came with standard features, such as black-finished cast aluminum wheels, a round headlight with a chromed ring, an analog and digital instrument cluster, a dual seat with a passenger grab rail, and a black-finished exhaust system with a chromed muffler.

As for performance, the 2004 Honda CB400SF Super Four took its muscles from 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.
