Murdercycles! Rating 200 2009 Motorcycles By Safety - Aprilia

 Aprilia ETV 1000 Caponord features a motor engineered as a 998 cc, water cooled, 60° v-twin. The motor's bore and stroke is 97 mm x 67.5 mm, and has a compression ratio of 10.4 :1. The engine cranks out a total of 98 horsepower. When this output is compared against the motorcycle's weight in kilograms of 215, which equates to 473 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 4.83. The final result is 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.

Aprilia Pegaso 650 is designed with an engine configured as a 660 cc, liquid cooled, single cylinder,. The engine features a bore and stroke of 100 mm x 84 mm, providing a compression ratio of 10:1. The engine generates a strong 48 horsepower. When this output is calculated to the bike's dry weight in kilograms of 168, which equals 369.6 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 7.7. 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.

Aprilia Pegaso 650 Factory bears an engine which is an 660 cc, liquid cooled, single cylinder,. The engine has a bore and stroke measuring 100 mm x 84 mm, equating to a compression ratio of 10:1. The engine is rated for a maximum of 48 horsepower. When this power at the rear wheel is taken into consideration alongside the dry weight in kilograms of 168, which converts out to 369.6 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 7.7. 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.

Aprilia Pegaso 650 Trail has an engine that is set up as an 659 cc, liquid cooled, single cylinder,. The motor has a bore and stroke of 100 mm x 84 mm, which results in a compression ratio of 10:1. The motor powers the rear wheel with a total of 50 horsepower. When this amount of horses is balanced with the dry weight in kilograms of 168, a mass that equals 369.6 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 7.39. That figure determines 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.

Aprilia RSV 1000 R is designed around an engine that is an 998 cc, liquid cooled, 60° v-twin. The engine is designed with a bore and stroke of 97 mm x 67.5 mm, which gives the engine a compression ratio of 11.8:1. The engine is able to generate a total of 143 horsepower. If you take that amount of power and equate it with the motorcycle's dry weight in kilograms of 185, a weight that is equivalent to 407 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 2.85. That figure equates out to 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.

Aprilia RSV 1000 R Factory is a motorcycle that has an engine which is an 998 cc, liquid cooled, 60° v-twin. The motor is engineered with a bore and stroke configuration of 97 mm x 67.5 mm, and has a compression ratio of 11.8:1. The powerplant creates a total of 143 horsepower. A simple calculation dividing that power to the total dry weight in kilograms of 185, a total dry weight which is equal to 407 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 2.85. That final calculation gives this motorcycle 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.

Aprilia Tuono 1000 R has an engine that is an 998 cc, liquid cooled, 60° v-twin. The motor's bore and stroke is 97 mm x 67.5 mm, providing a compression ratio of 11.8:1. The engine outputs a maximum of 139 horsepower. Those horses can be equated to the bike's weight in kilograms of 185, which in American units converts out to be 407 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 2.93. With that power to weight figure, this motorcycle can now be determined to have 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.

Aprilia Tuono 1000 R Factory features a motor engineered as a 998 cc, liquid cooled, 60° v-twin. The engine features a bore and stroke of 97 mm x 67.5 mm, equating to a compression ratio of 11.8:1. The engine cranks out a total of 139 horsepower. When a calculation is performed where that amount of horsepower is divided against the motorcycle's dry weight in kilograms of 181, which in Imperial measure equals 398.2 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 2.86. With that figure determined, it can now 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.

Hal, I think this is good information. I see a lot of big bore riders, and even the experienced ones come undone by pushing a bit hard.

In my shops we tried hard to keep inexperienced riders off the fast mounts.

I hope a lot of riders read your hubs.

A rider can get in well over their depth with many of the big-bore bikes.

Handling and brakes play a huge part in what goes wrong at high speed too. Some of the Japanese machinery handles very well, as do many Europeans

The "Hardly Ridable" Harley is not my choice for any sort of ride, not even cruising. Like I said they handle like a block of Apartments...or did I say a block of flats?

On the mountain roads where I live, rarely a summer's day goes by without having to scrape some novice rider on an overpowered bike off a guardrail or the grille of an 18 wheeler. In the vast majority of cases it's because the bozo was playing idiot boyracer on a public highway. In one case this summer, it was estimated that the rider was doing over 170 mph when he encountered the roadside cliff. As a FORMER Harley rider, I can certainly agree that Big Twins are hardly renowned for their rapier handling. :)
