Vehicle Information
Honda Nighthawk 450 Motorcycle - Street (1982-1986)
The Honda Nighthawk 450, officially known as the Honda CB450SC, was produced from 1982 to 1986. This mid-size standard motorcycle featured a retro-styled design and was powered by a robust parallel-twin engine. Its 447 cc air-cooled, four-stroke parallel-twin engine featured a single overhead camshaft (SOHC) and three valves per cylinder, fed by dual 34 mm carburetors. It delivered approximately 43 to 45 horsepower and 42 Nm of torque, transmitted via a six-speed manual gearbox and a chain final drive. While the core engine remained consistent, several updates and cosmetic changes were implemented across the model years. In 1982, it debuted with Comstar wheels and a speedometer calibrated to 137 km/h. By 1983, Comstar wheels were replaced with cast alloy wheels, and the speedometer was upgraded to read up to 169 km/h. The year 1985 saw the introduction of the CB450SCL variant specifically for the Californian market, designed to comply with stricter emissions regulations. The final year of production, 1986, brought minor cosmetic changes, such as body-colored fenders. FAQ:
