HONDA CB-1 400 (1989-1990) Specs, Performance & Photos

The Honda CB-1 was a small, naked, and lightweight motorcycle manufactured by Honda and first introduced in 1989. Compared to other motorcycles from the CB series, the CB-1 had its name written with a hyphen, while in other countries, it was marketed as the Honda CB400F.

The bike was originally developed for the Japanese market but also made its way to the American and Canadian markets. The last model was manufactured in 1990 and sold as leftover stock in 1992 with a discount.

The bike's engine was similar to the one used by the early CBR400RR, with changes to the port lengths and angles, smaller valves, and a lower compression ratio. Also, the gearbox suffered some changes, such as the primary and secondary gear ratios that reduced the 97 kph (60 mph) first gear down to around 48 kph (30 mph).

In the power department, the Honda CB-1 400 took its muscles from a 399cc four-stroke four-cylinder liquid-cooled engine fed by two Keihin carburetors that helped deliver an output power of 55 hp with maximum strength at 10,000 rpm and 39 Nm (29 lb-ft) of torque available at 9,500 rpm.

For suspension, the bike packed a 41 mm telescopic fork on the front and a Pro-Link monoshock absorber on the rear, while the stopping power was handled by a 310 mm disc with a four-piston caliper on the front wheel and a 240 mm disc squeezed by a single-piston caliper on the rear wheel.
