Honda CB-1 Motorcycle - Street (1989-1990)

The Honda CB-1, also known as the CB400F in some markets, is a compact naked sport motorcycle produced from 1989 to 1990. Designated with the model code NC27, it was powered by a liquid-cooled, DOHC inline-four engine with a displacement of 399 cc. This engine delivered 55 horsepower (41.1 kW) and 39 Nm of torque at 9,500 rpm, offering balanced performance for its class. During its short production run from 1989 to 1990, the Honda CB-1 was offered as a single "naked sport" model with no distinct trims (e.g., DX, LX). There were no significant mid-cycle generation or engine changes reported between the 1989 and 1990 model years. The engine, derived from the CBR400RR, was specifically re-tuned for the CB-1 with changes to port lengths, angles, smaller valves, and a lower compression ratio, along with modified primary and secondary gear ratios to enhance low and mid-range acceleration. These characteristics were inherent to the CB-1's design from its introduction. FAQ:
