Overview
The Honda CB 400SF is a naked motorcycle produced in 2019. Its 399 cm³ engine is a liquid-cooled, four-stroke, transverse DOHC four-cylinder, making 40 Nm of torque at 7,500 rpm; the motorcycle weighs 170 kg.
Peak torque arriving at 7,500 rpm means the engine needs revs to deliver its strongest pull. The front brake uses two 296 mm discs with four-piston calipers, while the rear has a single 240 mm disc; the four 32 mm carburetors supply fuel to the engine, and the chain final drive needs cleaning and adjustment.
