## How does the gearbox work?

Internal-combustion engines run at high speeds, so a reduction in gearing is necessary to transmit power to the drive wheels, which turn much more slowly. The gearbox provides a selection of gears for different driving conditions: standing start, climbing a hill, or cruising on level surfaces.

## What is the main function of a gearbox?

The purpose of a gearbox is to increase or reduce speed. As a result, torque output will be the inverse of the speed function. If the enclosed drive is a speed reducer (speed output is less than speed input ), the torque output will increase; if the drive increases speed, the torque output will decrease.

## What is the purpose of a gearbox?

Basically the gearbox serves three purposes: 1. To multiply (or increase) the torque (turning effort) being transmitted by the engine. 2. To provide a means of reversing the vehicle.

## What gears for what speed?

The gears determine the amount of power available from the engine. First gear provides the most pulling power but the least potential for speed, whilst fifth gear which provides the least pulling power allows the greatest range of speed.

## Which gearbox is used in two wheeler?
