Motorcycle Gearbox Working Principle

A motorcycle transmission has sequential gearing, meaning you can only go through the gears in order. Unlike a typical car transmission with an H-pattern gear selection, it is not possible to bypass gears on a sequential transmission. This type of transmission benefits the rider by allowing quick gear selection going up or coming down. Neutral is usually half a click between 1st gear and 2nd gear. Starting in neutral, the shift pattern can be remembered as “one down, four (or five) up,” but some transmissions are inverted to “one up, four (or five) down.”
Inside the transmission, there is an input shaft and an output shaft. The input shaft is tied to the engine and the output side is tied to the wheel. On each shaft are several gears which are in a constant mesh state. Some of the gears, called dog gears, are fixed to the shaft by a spline which allows them to slide and lock into other gears. The sliding of these gears is controlled by shift forks attached to the shift drum, which is a shaft with grooves. The shift drum is controlled by the foot pedal shifter. On the drum is a ratcheting mechanism with a groove notched out for the neutral position. The shafts are suspended in the case by bearings and everything gets lubricated with gear oil to prevent friction and damage.
