Old-style tank shift. Regular clutch hand Shifter - This is where the shifter is a regular knob either located on the tank, which operates through a linkage to the transmission (tank shifter) or on a lever bolted directly to the top of the transmission (jockey shifter or slap shifter depending on the transmission design) and involves the semi-complex task of foot clutch operation and hand ...
Underbone and miniature motorcycles often have a three to five-speed foot-shift lever, but the clutch is automatic (usually a centrifugal clutch). This type of clutchless (no manual clutch) transmission still must have the gears shifted manually by the rider, and the system is commonly known as a semi-automatic transmission.
[6] [110] [111] The conventional motorcycle foot shifter is retained, but the manual hand-clutch lever is no longer required. [112] [6] Semi-automatic transmissions in dirt bikes may be referred to as "automatic" despite a lack of automatic shifting. [113]
If the shifter is moved to a higher gear and the clutch is re-engaged quickly, the system will let the natural deceleration of the engine sync the drive train with the higher gear. If the clutch is depressed long enough for the engine to fall below the speed of the higher new gear, the computer will blip the throttle to bring the engine back to ...

A hand shifter is traditionally known as a jockey, tank, or police shifter depending on where it is mounted. "Suicide shifter" is a term that evolved out of the "suicide clutch." A suicide clutch is just a foot operated clutch that was popular during the days when bikes only had one foot-operated, rear brake.
Clutch control is the controlling of the speed of a manual transmission vehicle by partially engaging the clutch plate, using the clutch pedal instead of (or in conjunction with) the accelerator pedal. The purpose of a clutch is in part to allow such control; in particular, a clutch provides transfer of torque between shafts spinning at ...
A slipper clutch (also known as a back-torque limiter) is a specialized clutch with an integrated freewheel mechanism, developed for performance-oriented motorcycles to mitigate the effects of engine braking when riders decelerate.
