Before talking about functions and differences, we must know the definitions. Therefore, at this point, we'll answer a question that many bikers who are just starting out in this fantastic world ask themselves: What is a gearbox? Technically speaking, it's the element responsible for obtaining sufficient torque at the wheels to get the vehicle moving from a standstill, and once moving, obtaining sufficient torque at the wheels to overcome resistance to forward movement, mainly those derived from the aerodynamic profile, rolling friction, and uphill slopes. In simpler terms, it dictates how much force and speed are transmitted to the tires, allowing the motorcycle to start and ride on flat or steep terrain.

TYPES OF GEARBOX

MANUALS (MECHANICAL)

Manual transmissions, where gearshifts are performed by a manual mechanical control, using the clutch, which connects the engine to the gearbox. This group includes the DSG dual-clutch automated manual transmission and the DDCT dry dual-clutch automatic transmission.

AUTOMATIC (HYDROMATIC)

Automatic transmissions use a system that autonomously determines or decides the best relationship between engine power, speed, accelerator pressure, and resistance. An electrohydraulic device determines gear changes, while in the latest generation of transmissions, an electronic computer does so.

While a manual gearbox consists of pairs of cylindrical gears, an automatic transmission uses epicyclic gears in series or parallel to form the various gear ratios. The gearbox is responsible for shifting gears.
