1982 CM450A Hondamatic
Manufacturer	Honda
Model year	1982–1983
Class	Standard

The CM450A was a motorcycle made by Honda in 1982 and 1983. It was based on the CB400 and CM400 models (1978-1981), especially the CM400A Hondamatic (1980-1981). It had a 447cc SOHC parallel twin engine with two carburettors and a 2-speed transmission with a torque converter. It was not a full automatic, however, because the rider had to manually shift between low and high. It is called automatic because there is no clutch required due to the torque converter, and shared the Hondamatic trade name with Honda cars that had true automatic transmissions. The chain-driven CM450A had a top speed of 90 miles per hour (140 km/h) and weighed 413 pounds (187 kg).^[1] Both models had a front disc brake and a rear drum brake. The suspension consisted of two shocks in the rear and telescoping shock-absorbing front forks. The gas tank had a 3.4 US gallons (13 l; 2.8 imp gal) capacity. The exhaust was routed through a separate pipe and baffle on each side of the motorcycle, although both exhaust pipes shared a plenum under the motor. It had an electric start with a kick start as well.
