How does a dirt bike gearbox work?
So for most of us the gearbox is a clutch and a lever on the left side of the bike. As you shift the gear lever, it mechanically moves a drum in the gearbox that in turn engages one of three (in a six-speed box) “selector forks”. These selector forks are mounted on two shafts, along with the cogs or gears.
How does a motorcycle clutch and transmission work?
A mechanism uses the rider’s pull on the clutch lever to lift the pressure plate against its spring pressure, separating the friction and steel plates. When you have started the engine and wish to depart, you pull in the clutch lever, then click the transmission into first gear with your foot.

How does a sequential gearbox work on a motorcycle?
If you have ever ridden a motorcycle, you know that the manual transmission in a motorcycle is nothing like this. On a motorcycle, you shift gears by clicking a lever up or down with your toe. It is a much faster way to shift. This type of transmission is called a sequential gearbox or a sequential manual transmission. Transmission Image Gallery.
Is the gearbox a part of the transmission?
A gearbox is technically a component of the transmission. The gearbox is an enclosed gear train, while the transmission is the entire power transmission system (including the gearbox). Cite This!
How are gears engaged in a motorcycle transmission?
The gears are engaged by shifting a lever, which moves shifting forks inside the transmission. This content is not compatible on this device. The job of a clutch is to engage and disengage power from the engine crankshaft to the transmission.
Is there a synchromesh gearbox on a motorcycle?
Most manual motorcycle gearboxes have “constant mesh” gears which are always mated but may rotate freely on a shaft until locked by a toothed sliding collar or “dog clutch”. Since the gears are always rotating and can only be accessed sequentially, synchromesh is not generally needed.

Where are the control rods located in a gearbox?
If the drum is located away from the transmission’s gears, the grooves control standard control rods. If the drum is located next to the gears, the grooves directly move the gear selector fork, and no control rods are needed. This seems to be the more common technique because it has fewer parts and is more compact.
