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:
“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)
“I lay my eternal curse on whomsoever shall now or at any time hereafter make schoolbooks of my works and make me hated as Shakespeare is hated. My plays were not designed as instruments of torture. All the schools that lust after them get this answer, and will never get any other.”
—George Bernard Shaw (1856–1950)
“We are all instruments endowed with feeling and memory. Our senses are so many strings that are struck by surrounding objects and that also frequently strike themselves.”
—Denis Diderot (1713–84)
