HONDACB400SF Super Four 2007 - 2008

　　In 2008, the Japanese motorcycle manufacturer introduced the CB400SF Super Four, a standard machine that was suitable for both inexperienced and young riders who wanted an introductory bike, as well as for the more seasoned ones who wanted a fuel-efficient and agile commuter.

　　The 2008 model introduced several upgrades, such as a Honda PGM-FI programmed fuel injection system and an idle control valve that improved fuel economy and reliability. The engine featured revised materials and an integrated crankcase cover that reduced engine weight by two kg (4.4 lbs).

　　The VTEC operation was refined, with four valves engaged at 6,300 rpm from first to fifth gear with the throttle wide open, while in sixth gear at 6,750 rpm one exhaust and one intake valve were shut down.

　　Also, the bike featured an independent cylinder ignition timing map, a revised air intake geometry, and a larger stainless steel muffler that contributed to more fuel efficiency. The updated frame rigidity and engine mounting position improved handling.

　　The bike was available with optional ABS that featured three-piston sliding calipers on the front instead of the standard four-piston and a larger 256 mm rear brake disc, while the overall weight was increased by four kg (8.8 lbs) on the standard model and by nine kg (20 lbs) on the ABS version.

　　In the power department, the 2008 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.
