sentences:  The Kawasaki 454 is well known for its acceleration, having raced against a 454 LS big block Chevrolet Corvette and beating it to both 0-60 and the quarter mile by more than a second.Despite the 440 being its predecessor in the sale of middle-size-displacement motorcycles designed by Kawasaki, the two shared almost nothing in design, as the Kawasaki 440 had a single overhead camshaft and had only two valves per cylinder, and was air-cooled, producing 41 horsepower to the 454's 50 horsepower.Both motorcycles were highly reliable and low maintenance, but for different reasons, as the 440 was just a very simple machine to service, and the 454 needed little maintenance over time as a result of its belt drive.
