Instruments
Most road motorcycles have an instrument panel, usually consisting of speedometer, odometer and tachometer.
Fuel gauges are becoming more common, but traditionally a reserve tank arrangement is used with a petcock (petrol tap) on the side of the motorcycle allowing the rider to switch to a reserve fuel supply when the main fuel supply is exhausted. There is not actually a separate reserve tank: The intake for the petcock has two pipes, one extending higher into the fuel tank than the other. When fuel no longer covers the longer pipe the engine will lose power/splutter and the rider switches the petcock to the "reserve" setting, which accesses the shorter pipe. Riders whose bikes lack a fuel gauge (most machines prior to the past few years) usually learn how far they can go with a full tank of fuel, and then use a trip meter if available to judge when they must refill the tank.

Famous quotes containing the word instruments:
“But when to mischiefmortals bend their will,
How soon they find fit instruments of ill!”
—Alexander Pope (1688–1744)
“Water, earth, air, fire, and the other parts of this structure of mine are no more instruments of your life than instruments of your death. Why do you fear your last day? It contributes no more to your death than each of the others. The last step does not cause the fatigue, but reveals it. All days travel toward death, the last one reaches it.”
—Michel de Montaigne (1533–1592)
“The universe appears to me like an immense, inexorable torture-garden.... Passions, greed, hatred, and lies; law, social institutions, justice, love, glory, heroism, and religion: these are its monstrous flowers and its hideous instruments of eternal human suffering.”
—Octave Mirbeau (1850–1917)
