The Honda CB450 is a standard motorcycle made by Honda from 1965 to 1974 with a 444 cc (27.1 cu in) 180° DOHC straight-twin engine. Producing 45 bhp (some 100 bhp/ litre), it was Honda's first "big" motorcycle, though it did not succeed in its goal of competing directly against the larger Triumphs, Nortons, and Harley-Davidsons in the North American market at the time.[3] As a result, Honda tried again, leading to the development of the four cylinder Honda CB750 that marked a turning point for Honda and beginning of the "superbike" era of motorcycles.[4][5][6]
