Torque – 1. The tendency of a force to cause an object to rotate. In an engine, the torque is expressed as the force applied multiplied by the distance from the center of rotation. It is the basic measure of the propulsive effect of a powered wheel. Or, said in other words: The measure of the force applied to produce rotational motion usually measured in foot-pounds or Nm. Torque is determined by multiplying the applied force by the distance from the pivot point to the point where the force is applied. 2. Measure of force producing torsion and rotation around an axis. A measurement of engine power described as the ability to turn or twist. Maximum torque is produced wen an engine is operating at maximum combustion efficiency. 3. A twisting force, and in a motorcycle it is a measure of the leverage the engines exerts on the rear wheel. 4. Turning force, so a measurement of force multiplied by distance. Typically expressed in units of pound-feet (lb-ft (not lb/ft)) or Newton-metres (Nm). Diesels generally develop more torque than petrols and at much lower rpm (engine ‘revolutions per minute’)

Torque Lb-ft – Torque is the rotational equivalent to force measured in pound-feet and is essentially the Engine ‘pulling’ power. High torque is of benefit for vehicles needed for towing, or for performance driving.

Two second rule – This is the minimum spacing in seconds between moving motorcycles. While in formation, maintain a 2-second interval from the rider in front of you. It is measured by counting “one-thousand one, one-thousand two” as you see the rider in front of you pass a sign or landmark. Stop counting when you pass the same marker. Under poor weather conditions, maintain longer intervals consistent with safety.

Two Stroke – Two Stroke Engine – 1. Mechanically simple, light and powerful, two stroke engines combine the exhaust and intake strokes, making every other stroke a power stroke. 2. An engine (also called a stroker) who’s power cycle consists of just two movements, or strokes: The piston moves down, drawing in the fuel air charge, and then up, cumbusting the charge. Unfortunately two stroke engines typically produce much more pollution than a four stroke design.
