In 2008, the Japanese motorcycle manufacturer launched the CB400 Super Bol D'Or, a half-faired version of the CB400 Super Four, which compared to the naked machine, featured an additional front cowl with a rectangular headlight and a small tinted windscreen.
The 2008 Super Bol D'Or came with the same specifications and upgrades brought upon the naked version, such as a Programmed Fuel Injection (PGM-FI) system and an idle control valve that improved fuel economy and reliability.
The engine featured revised materials and an integrated crankcase that reduced the overall engine weight by two kg (2.2 lbs), while an independent cylinder ignition timing map, a revised intake geometry, and a larger stainless steel muffler improved fuel efficiency.
Right from the factory, the Super Bol D'Or came equipped with standard features, such as three-spoke cast aluminum wheels, a one-piece two-up seat with a passenger grab handle, a half fairing, an aggressive color scheme, a black-finished steel frame, and a digital and analog instrument cluster.
In the center of the steel cradle frame, the 2008 Honda CB400 Super Bol D'Or packed a 399cc four-stroke four-cylinder liquid-cooled engine, which received fuel to the pistons through a PGM-FI system that helped deliver an output power of 53 hp with maximum strength at 11,000 rpm and 40 Nm (30 lb-ft) of torque available at 7,500 rpm.
