Modern motorcycles normally have five or six forward gears. Only the largest touring motorcycles (most prominently, the [[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.
