Murdercycles! Rating 200 2009 Motorcycles By Safety - Kawasaki 650cc to 1 Litre

Updated on November 30, 2008

 Kawasaki W 650 is designed with an engine configured as a 676 cc, air cooled, twin. The motor is engineered with a bore and stroke configuration of 72 mm x 83 mm, which results in a compression ratio of 8.7:1. The engine generates a strong 50 horsepower. When this amount of horses is balanced with the dry weight in kilograms of 195, which equals 429 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 8.58. Those figures provide 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 750 is designed around an engine that is an 738 cc, air cooled, 4 - cylinders in line. The engine has a bore and stroke measuring 66 mm x 54 mm, providing a compression ratio of 9.5:1. The engine is able to generate a total of 68 horsepower. Those horses can be equated to the bike's weight in kilograms of 204, a weight that is equivalent to 448.8 pounds, the pounds per horsepower can now be precisely measured in a determination which is a very accurate reflection of this particular motorcycle's total performance on the street or track. In the case of this bike, the power to weight ratio is 6.6. That figure equates out to a Murdercycle Rating of "E": HAZARD which means that if this motorcycle absolutely has to be operated on public highways, then it should be ridden only by a mature, skilled adult with extensive experience and superb judgment.

Kawasaki ZR-7 S has an engine that is an 738 cc, air cooled, 4 - cylinders in line. The engine is designed with a bore and stroke of 66 mm x 54 mm, which results in a compression ratio of 9.5:1. The engine outputs a maximum of 67 horsepower. When this maximum power generation is divided by the vehicle's dry weight in kilograms of 209, which in American units converts out to be 459.8 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 6.86. With that power to weight figure, this motorcycle can now be determined to have a Murdercycle Rating of "E": HAZARD which means that if this motorcycle absolutely has to be operated on public highways, then it should be ridden only by a mature, skilled adult with extensive experience and superb judgment.

Kawasaki ZX-7R has an engine that is set up as an 748 cc, water cooled, 4 - cylinders in line. The engine has a bore and stroke measuring 73 mm x 44.7 mm, equating to a compression ratio of 12.5:1. The motor powers the rear wheel with a total of 122 horsepower. When this power at the rear wheel is taken into consideration alongside the dry weight in kilograms of 203, which converts out to 446.6 pounds, the calculation of pounds per horsepower is now possible: a measurement that is generally utilized to determine the motorcycle's overall performance. In this case, the power to weight ratio is 3.66. Therefore, it can be concluded that this bike has a Murdercycle Rating of "C": EXCESSIVE which means that it should only be operated on a racetrack by at least amateur racers who already have gained a measure of experience, and never on a public highway.

Kawasaki Z750 ABS bears an engine which is an 748 cc, liquid cooled, 4 - cylinders in line. The motor's bore and stroke is 68.4 mm x 50.9 mm, which gives the engine a compression ratio of 11.3:1. The engine is rated for a maximum of 106 horsepower. If you take that amount of power and equate it with the motorcycle's dry weight in kilograms of 207, which converts out to 455.4 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 4.3. That results in a Murdercycle Rating of "C": EXCESSIVE which means that it should only be operated on a racetrack by at least amateur racers who already have gained a measure of experience, and never on a public highway.

Kawasaki ZX-9R is designed around an engine that is an 899 cc, liquid cooled, 4 - cylinders in line. The motor has a bore and stroke of 75 mm x 50.9 mm, which results in a compression ratio of 12.2:1. The engine is able to generate a total of 144 horsepower. When this amount of horses is balanced with the dry weight in kilograms of 186, a mass that equals 409.2 pounds, the pounds per horsepower can now be precisely measured in a determination which is a very accurate reflection of this particular motorcycle's total performance on the street or track. In the case of this bike, the power to weight ratio is 2.84. This final analysis shows that this motorcycle has 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 Z 1000 ABS has an engine that is set up as an 953 cc, liquid cooled, 4 - cylinders in line. The engine features a bore and stroke of 77.2 mm x 50.9 mm, and has a compression ratio of 11.2:1. The motor powers the rear wheel with a total of 125 horsepower. A simple calculation dividing that power to the total dry weight in kilograms of 209, a mass that equals 459.8 pounds, the calculation of pounds per horsepower is now possible: a measurement that is generally utilized to determine the motorcycle's overall performance. In this case, the power to weight ratio is 3.68. That figure determines that this motorcycle has a Murdercycle Rating of "C": EXCESSIVE which means that it should only be operated on a racetrack by at least amateur racers who already have gained a measure of experience, and never on a public highway.

Kawasaki ZX-10R is a motorcycle that has an engine which is an 998 cc, liquid cooled, 4 - cylinders in line. The engine is designed with a bore and stroke of 76 mm x 55 mm, which gives the engine a compression ratio of 12.9:1. The powerplant creates a total of 200 horsepower. If you take that amount of power and equate it with the motorcycle's dry weight in kilograms of 179, a weight that is equivalent to 393.8 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 1.97. This figure means that this motorcycle has a Murdercycle Rating of "A": EXTREME which means that it is unsafe for anyone except for highly trained professional riders with years of experience on major racetracks!
