Honda CM450A

The Honda CM450A is a motorcycle made by Honda in 1982 and 1983, based on the CB400 and CM400 models and especially the CM400A Hondamatic. It had a 447 cc SOHC parallel twin with two carburettors and a two-speed transmission with a torque converter. It was not a full automatic, since the rider had to shift manually between low and high, but it needed no clutch, and it shared the Hondamatic name with Honda cars that had true automatic transmissions. The chain-driven bike had a top speed of 90 mph, weighed 413 pounds and carried 3.4 US gallons of fuel, with a front disc and rear drum brake, a separate exhaust pipe and baffle on each side sharing a plenum under the motor, and both electric and kick start.
