"TORQUE"                     MYSTERIES EXPLAINED!!!       

If you put 50 pounds of pressure on the end of a foot-long wrench, you are exerting 50 foot-pounds of force. If that force tends to cause rotation, as a wrench does it on a bolt, that force is called torque.

In an engine, the pressure of combustion above the piston tries to force the piston and its connecting rod downward, which then attempt to make the crankshaft rotate. That force is called torque. If torque succeeds in turning the crankshaft, the resultant movement is called work.

Two bikes make the same peak horsepower, but in drastically different ways. The Harley produces bundles of torque at low rpm, while a Nippon racer makes a small amount of torque at extremely high rpm. The end result is exactly the same horsepower, but there are no similiarities whatsoever in the way the two behave when being ridden.

The Harley torque curve takes you off and stay there, the other will make you grin.

Such a upshot can be achieved only by 74-or-more (cubic inches of displacement).
