Murdercycles! Rating 200 2009 Motorcycles By Safety - Yamaha Over 1.3 Litres

 Yamaha Road Star has an engine that is an 1602 cc, air cooled, v-twin. The motor has a bore and stroke of 95 mm x 113 mm, and has a compression ratio of 8.3:1. The engine outputs a maximum of 90 horsepower. A simple calculation dividing that power to the total dry weight in kilograms of 312, a mass that equals 686.4 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 7.63. With that number finally determined, we can now conclude 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.

Yamaha MT-01 is designed around an engine that is an 1670 cc, air cooled, v-twin. The engine features a bore and stroke of 97 mm x 113 mm, which results in a compression ratio of 8.3:1. The engine is able to generate a total of 90 horsepower. When this amount of horses is balanced with the dry weight in kilograms of 243, which equals 534.6 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 5.94. This final analysis shows that this motorcycle 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.

Yamaha Road Star Warrior features a motor engineered as a 1670 cc, air cooled, v-twin. The engine is designed with a bore and stroke of 97 mm x 113 mm, providing a compression ratio of 8.3:1. The engine cranks out a total of 86 horsepower. Those horses can be equated to the bike's weight in kilograms of 275, a weight that is equivalent to 605 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 7.03. The final result is that this motorcycle has 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.

Yamaha Roadliner is designed with an engine configured as a 1854 cc, air cooled, 48° v-twin. The motor is engineered with a bore and stroke configuration of 100 mm x 118 mm, equating to a compression ratio of 9.4:1. The engine generates a strong 90 horsepower. When a calculation is performed where that amount of horsepower is divided against the motorcycle's dry weight in kilograms of 319, a total dry weight which is equal to 701.8 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 7.8. 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.

Yamaha Stratoliner S is a motorcycle that has an engine which is an 1854 cc, air cooled, 48° v-twin. The motor has a bore and stroke of 100 mm x 118 mm, providing a compression ratio of 9.4:1. The powerplant creates a total of 90 horsepower. When this output is calculated to the bike's dry weight in kilograms of 344, which equals 756.8 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 8.41. 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.
