HONDACB400SF Super Four 2002 - 2003

　　In 2003, the Japanese motorcycle manufacturer launched the CB400SF Super Four, a standard motorcycle part of the CB series that first saw the light of day in 1992 at the Kumamoto plant as an embodiment of the typical Universal Japanese Motorcycle (UJM), updated with modern technology.

　　The 2003 model featured the same updates as the 2002 model, with changes to the VTEC technology set to trigger at 6,300 rpm along with an updated ignition timing map. In addition, it featured an LCD odometer, trip meter, a clock, and a fuel gauge integrated into the speedometer and tachometer faces and a Honda Ignition Security System (HISS).

　　The air intake noise was reduced by enhancing the air cleaner box’s surface and packing a lighter and smaller oil filter. On the front wheel, the bike borrowed the front calipers from the CBR900RR and added chipping guards to the front fork tubes, which increased the overall weight by one kg (2.2 lbs).

　　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.

　　As for power, the 2003 Honda CB400SF Super Four had its heartbeat set 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.
