Modern motorcycles normally have five or six forward gears. Only the largest touring motorcycles (most prominently, the [[:Category:Honda GL series|Honda Goldwing]]) and a few models that are routinely used with a [[sidecar]] are fitted with a reverse gear. | Modern motorcycles normally have five or six forward gears.

The clutch is typically an arrangement of plates stacked in alternating fashion, one geared on the inside to the engine, and next geared on the outside to the transmission input shaft. Whether wet (rotating in engine oil) or dry, the plates are squeezed together by a spring, causing friction buildup between the plates until they rotate as a single unit, driving the transmission directly. A lever on the handlebar, through a cable or hydraulic arrangement, uses mechanical advantage to release the clutch spring, allowing the engine to freewheel with respect to the transmission. | The clutch is typically an arrangement of plates stacked in alternating fashion, one geared on the inside to the engine, and next geared on the outside to the transmission input shaft.

The most commonly used transmission is a sequential gearbox. From neutral, either first or second gear can be selected, but higher gears may only be accessed in order - it is not possible to shift from second gear to fourth gear, without shifting through third gear. | The most commonly used transmission is a sequential gearbox.
