Murdercycles! Rating 200 2009 Motorcycles By Safety - Kawasaki Under 650cc

Updated on November 30, 2008

  Kawasaki ZZR 250 bears an engine which is an 248 cc, liquid cooled, twin. The engine has a bore and stroke measuring 64 mm x 41.2 mm, which results in a compression ratio of 12.4:1. The engine is rated for a maximum of 35 horsepower. When this maximum power generation is divided by the vehicle's dry weight in kilograms of 148, which equates to 325.6 pounds, it is now possible to determine the ratio of pounds per horsepower, which is a good way to estimate the motorcycle's actual performance in everyday use. This bike's power to weight ratio is 9.3. That results in a Murdercycle Rating of "F": HIGH-RISK which means that this bike is too powerful for public highways and that any non-professional rider operating it is taking a high degree of risk.

Kawasaki Ninja 250R is a motorcycle that has an engine which is an 249 cc, liquid cooled, 2 - cylinders in line. The engine has a bore and stroke measuring 62 mm x 41.2 mm, and has a compression ratio of 11.6:1. The powerplant creates a total of 33 horsepower. When this output is compared against the motorcycle's weight in kilograms of 154, which in American units converts out to be 338.8 pounds, the actual ratio of this motorcycle's actual performance while being ridden can be determined with a high degree of accuracy. The pounds per horsepower determines what the power to weight ratio is, and in this bike's case, that figure is 10.27. This figure means that this motorcycle has a Murdercycle Rating of "G": OVER-POWERED which means that even a rider with a couple of years of street experience on a smaller displacement motorcycle should exercise caution as this bike is powerful enough to get them into trouble.

Kawasaki ZXR 400 is designed with an engine configured as a 398 cc, water cooled, 4 - cylinders in line. The engine features a bore and stroke of 57 mm x 39 mm, equating to a compression ratio of 12.1:1. The engine generates a strong 65 horsepower. When a calculation is performed where that amount of horsepower is divided against the motorcycle's dry weight in kilograms of 159, which in Imperial measure equals 349.8 pounds, we can now calculate the ratio of pounds per horsepower, a fairly standard calculation in the motor vehicle world which will allow you to determine the motorcycle's actual performance on the street. In the case of this bike, its power to weight ratio is 5.38. Those figures provide a Murdercycle Rating of "D": MENACE which means that this motorcycle should never be operated on public highways but would be suitable for a privateer racetrack rider.

Kawasaki ZRX 400 II features a motor engineered as a 399 cc, water cooled, 4 - cylinders in line. The motor is engineered with a bore and stroke configuration of 57.5 mm x 38.5 mm, which gives the engine a compression ratio of 11.2:1. The engine cranks out a total of 53 horsepower. When that total amount of power at maximum levels is divided by the motorcycle's dry weight in kilograms of 186, which in Imperial measure equals 409.2 pounds, we end up with a calculation of pounds per horsepower, which is an industry standard manner of determining the overall real world power of the vehicle. In this motorcycle's case, the power to weight ratio is 7.72. With that figure determined, it can now be concluded that this bike has a Murdercycle Rating of "F": HIGH-RISK which means that this bike is too powerful for public highways and that any non-professional rider operating it is taking a high degree of risk.

Kawasaki Zephyr X is a motorcycle that has an engine which is an 399 cc, liquid cooled, 4 - cylinders in line. The motor has a bore and stroke of 57.5 mm x 38.5 mm, equating to a compression ratio of 10.3:1. The powerplant creates a total of 53 horsepower. When a calculation is performed where that amount of horsepower is divided against the motorcycle's dry weight in kilograms of 186, a total dry weight which is equal to 409.2 pounds, the actual ratio of this motorcycle's actual performance while being ridden can be determined with a high degree of accuracy. The pounds per horsepower determines what the power to weight ratio is, and in this bike's case, that figure is 7.72. That final calculation gives this motorcycle a Murdercycle Rating of "F": HIGH-RISK which means that this bike is too powerful for public highways and that any non-professional rider operating it is taking a high degree of risk.

Kawasaki ZX-6R bears an engine which is an 599 cc, liquid cooled, 4 - cylinders in line. The engine features a bore and stroke of 67 mm x 42.5 mm, providing a compression ratio of 13.9:1. The engine is rated for a maximum of 131 horsepower. When this output is calculated to the bike's dry weight in kilograms of 167, which equals 367.4 pounds, it is now possible to determine the ratio of pounds per horsepower, which is a good way to estimate the motorcycle's actual performance in everyday use. This bike's power to weight ratio is 2.8. This motorcycle is thereby generating a power to weight ratio which gives it a Murdercycle Rating of "B": HIGH-DANGER which means that no one other than a motorcycle racer with at least a year or so of experience should ride it, and then only on a race or test track.

Kawasaki Versys has an engine that is an 649 cc, liquid cooled, 2 - cylinders in line. The motor has a bore and stroke of 83 mm x 60 mm, providing a compression ratio of 10.6:1. The engine outputs a maximum of 64 horsepower. When this output is calculated to the bike's dry weight in kilograms of 181, which in Imperial measure equals 398.2 pounds, the calculation can now be executed which shows the power to weight ratio as expressed as pounds of the motorcycle's dry weight which is driven by each horsepower. This bike's pounds per horsepower result is 6.22. With that number finally determined, we can now conclude that this bike has a Murdercycle Rating of "D": MENACE which means that this motorcycle should never be operated on public highways but would be suitable for a privateer racetrack rider.
