Which Go-Karts Typically Have Reverse?

Electric go-karts commonly feature a reverse gear, which can be beneficial during spins or crashes on the track, allowing drivers to back up without external help.

Conversely, rental and professional racing go-karts usually lack this function to maintain a lightweight design and speed efficiency.

That said, a reverse gearbox can be installed on go-karts if the need for a reverse option arises. Thus, while reverse is not a standard feature in all go-karts, it is typically found in electric models and can be added to others with specific modifications.

The Mechanism Behind Go-Karts

The functioning of a go-kart is rooted in the intricate movements of pistons within the engine cylinders.

These movements spin the crankshaft, leading to the rotation of the axle that propels the wheels, thus accelerating the go-kart.

Go-karts typically utilise a 2-stroke engine linked with a direct drive system that powers the rear axle.

The system consists of a spark plug, a carburettor, 2-stroke oil, and a clutch that facilitates connection.

The power transfer from the engine to the rear axle is carried out via a chain, although some rental models use a belt instead.

Additionally, four-stroke engines, usually standard air-cooled industrial types, can also be found in go-karts.

How You Can Tell if Your Go-Kart Has Reverse

Discerning whether your go-kart possesses reverse capabilities can often be determined by the presence of a gear shift. In general, petrol go-karts without a gear shift are likely lacking in reverse capabilities.

Conversely, if your go-kart is equipped with a reverse gearbox - a critical component for enabling reverse in gas go-karts - it's identified as a "shifter go-kart", indicating it does have reverse capabilities.

These types of go-karts will typically feature gearboxes and manual transmissions.

How Can You Add Reverse to Petrol Go-Karts?

It's possible to add a reverse option to your petrol go-kart. This typically involves installing a reverse gearbox.

This topic is covered in more depth in our guide on go-kart clutches explained.
