HONDACB400SF Super Four 2000 - 2001

　　The Honda CB400SF Super Four was a standard motorcycle part of the CB series made by Honda at the Kumamoto plant in 1992 and embodied the typical Universal Japanese Motorcycle (UJM) manufactured through the 1970s, but with modern technology.

　　In 2001, the Japanese motorcycle manufacturer launched the CB400SF Super Four, a bike that came with major improvements thanks to Honda's VTEC technology, topped by a lightweight aluminum muffler, 40 mm shorter wheelbase, 10 mm lower engine mount positions, and the front suspension borrowed from the CBR900RR machine that improved handling and reduced the overall weight by six kg (13 lbs).

　　The engine featured four valves per cylinder, but below 6,750 rpm, only one intake and one exhaust valves were in function, and after 6,750 rpm, the remaining two valves jumped in. This technique improved the low and mid-range power and efficiency.

　　The 2001 Honda CB400SF Super Four had its soul brought to life 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.

　　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.
