Murdercycles! Rating 200 2009 Motorcycles By Safety - Yamaha 650cc to 1 Litre
Yamaha XT 660 R bears an engine which is an 659 cc, liquid cooled, single cylinder,. The engine features a bore and stroke of 100 mm x 84 mm, and has a compression ratio of 10:1. The engine is rated for a maximum of 48 horsepower. A simple calculation dividing that power to the total dry weight in kilograms of 172, a total dry weight which is equal to 378.4 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 7.88. This motorcycle is thereby generating a power to weight ratio which gives it 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-03 is a motorcycle that has an engine which is an 660 cc, liquid cooled, single cylinder,. The engine has a bore and stroke measuring 100 mm x 84 mm, which gives the engine a compression ratio of 10:1. The powerplant creates a total of 48 horsepower. If you take that amount of power and equate it with the motorcycle's dry weight in kilograms of 174, which converts out to 382.8 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 7.98. This figure means that this motorcycle 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 YZF-R1 has an engine that is an 998 cc, liquid cooled, 4 - cylinders in line. The motor is engineered with a bore and stroke configuration of 77 mm x 53.6 mm, which gives the engine a compression ratio of 12.7:1. The engine outputs a maximum of 180 horsepower. When that total amount of power at maximum levels is divided by the motorcycle's dry weight in kilograms of 177, which equals 389.4 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 2.16. With that number finally determined, we can now conclude that this bike 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!
Yamaha FZ1 has an engine that is set up as an 998 cc, liquid cooled, 4 - cylinders. The motor's bore and stroke is 77 mm x 53.6 mm, equating to a compression ratio of 11.5:1. The motor powers the rear wheel with a total of 150 horsepower. When this power at the rear wheel is taken into consideration alongside the dry weight in kilograms of 194, which equates to 426.8 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 2.85. Therefore, it can be concluded that this bike 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.
