HONDACB400SF Super Four 1999 - 2000

　　In 2000, the Japanese motorcycle manufacturer launched the Honda CB400SF Super Four, a standard motorcycle part of the CB series powered by an updated version of the engine used by the CB-1 machine and with the looks of the typical Universal Japanese Motorcycle (UJM) built in the 1970s.

　　In 1994, the bike received its first upgrade that included the updated ignition timing due to the adoption of the pent-roof combustion chamber design, the internal structure of the muffler, and the cam chain links that reduced the mechanical noise.

　　In 1995, the bike came with more cooling fins on the lower part of the cylinder bank and in a special edition R version that featured PGM-IG programmed ignition timing along with an electronically controlled valve, an additional headlight cowl, a sharper rake angle, a lightweight aluminum muffler, stiffer suspension, and sintered brake pads.

　　In 1996, the Super Four came with new front discs with a reduced tendency to warp and four-piston calipers for improved braking response but also in a special edition S version that featured a Brembo braking system and Showa suspension.

　　The 2000 Honda CB400SF Super Four machine took its muscles from a 399cc four-stroke four-cylinder liquid-cooled engine used from its debut 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.
