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

Updated on November 30, 2008

 Honda XR 250 Motard has an engine that is set up as an 249 cc, air cooled, single cylinder. The motor's bore and stroke is 73 mm x 59.5 mm, which results in a compression ratio of 9.3:1. The motor powers the rear wheel with a total of 28 horsepower. When this maximum power generation is divided by the vehicle's dry weight in kilograms of 120, a weight that is equivalent to 264 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 9.43. Therefore, it can 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.

Honda XR 400 Motard is designed around an engine that is an 397 cc, air cooled, single cylinder. The engine features a bore and stroke of 85 mm x 70 mm, which gives the engine a compression ratio of 8.8:1. The engine is able to generate a total of 30 horsepower. When that total amount of power at maximum levels is divided by the motorcycle's dry weight in kilograms of 131, a total dry weight which is equal to 288.2 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 9.61. This final analysis shows 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.

Honda CB 400 Super Four is a motorcycle that has an engine which is an 399 cc, liquid cooled, 4 - cylinders in line. The engine is designed with a bore and stroke of 55 mm x 42 mm, equating to a compression ratio of 11.3:1. The powerplant creates a total of 53 horsepower. When this power at the rear wheel is taken into consideration alongside the dry weight in kilograms of 170, which converts out to 374 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 7.06. This figure means 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.

Honda CBF 500 ABS has an engine that is an 499 cc, liquid cooled, twin. The motor's bore and stroke is 73 mm x 59.6 mm, and has a compression ratio of 11.6:1. The engine outputs a maximum of 57 horsepower. When this output is compared against the motorcycle's weight in kilograms of 189, which converts out to 415.8 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 7.29. 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.

Honda CB 600 F Hornet ABS has an engine that is an 599 cc, liquid cooled, 4 - cylinders in line. The motor is engineered with a bore and stroke configuration of 67 mm x 42.5 mm, which results in a compression ratio of 12:1. The engine outputs a maximum of 102 horsepower. When this amount of horses is balanced with the dry weight in kilograms of 177, a mass that 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 3.82. With that number finally determined, we can now conclude 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.

Honda CBR 600 RR is designed with an engine configured as a 599 cc, liquid cooled, 4 - cylinders in line. The engine has a bore and stroke measuring 67 mm x 42.5 mm, equating to a compression ratio of 12.2:1. The engine generates a strong 118 horsepower. When this power at the rear wheel is taken into consideration alongside the dry weight in kilograms of 184, a weight that is equivalent to 404.8 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 3.43. Therefore, this motorcycle has earned 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.

Honda FMX 650 has an engine that is an 644 cc, air cooled, single cylinder. The engine features a bore and stroke of 100 mm x 82 mm, equating to a compression ratio of 8.3:1. The engine outputs a maximum of 37 horsepower. When a calculation is performed where that amount of horsepower is divided against the motorcycle's dry weight in kilograms of 163, which equals 358.6 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 9.69. With that number finally determined, we can now conclude that this bike 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.

      Bill Mc, you might want to read my Hubs on the subject:

      and

      They will give you a broader insight into my position on excessive motorcycle speed on public roads.

      I guess you would consider my Triumph Thruxton a hazard of some degree (weight to power ratio 6.53 lbs.to 1 hp ) but the bike is very managable and the torque is controllable. Come to think of it, just how fast I go is determined by my right wrist and my brain - how quickly I decide to twist the throttle. That is something you fail to consider in your ratings as well as the over all controllability of the machine.
