How to Build a Kart Cross

by Erick Kristian

A kart cross or off-road go kart is a go kart that is designed specifically for off-road use. It has large tires and an off-road suspension and a higher ride height than track karts. The kart cross carts are typically more powerful as well, because they are larger and heavier. The exact method of constructing a kart cross kart will vary depending on the parts chosen. A build guide is recommended for the specific step-by-step details.

Step 1

Select a chassis. The chassis should be designed for kart cross and be large enough to accommodate the type of engine you desire. The chassis can easily be painted, so color is not a factor.

Step 2

Select an engine. The engine size depends on how large and powerful you want the cross kart to be. Most kart cross engines are between 600 and 1000 cc. Use a dirt bike engine because they are designed for high performance driving and are durable.

Step 3

Select a transmission and drive train. The transmission should be a six-speed sequential transmission. For performance, also purchase a steering wheel equipped with paddle shifters.

Step 4

Purchase a suspension system. The suspension must be a kart cross suspension designed for off-road use. The suspension is vital to staying controlled on rough terrain. An adjustable suspension is best because it allows the driver to adjust the suspension for different types of terrain and riding styles.

Step 5

Purchase wheels and tires. The wheels and tires on a kart cross kart are generally large, heavily treaded and durable. Larger wheels are generally better because they retain more grip and give a more comfortable ride.

Step 6

Purchase seats. Some karts are single seaters, some are dual. Off-road racing karts are only single. There is some debate about seat choices. Many riders prefer a harder racing style seat, while others prefer a more padded seat. A combination seat --- one that has both --- is best. It has the contours and form of a racing seat with an inch of safety padding. Many seats come with a four-point belt harness. This is necessary.

Step 7

Purchase brakes. The brakes for the kart should be large and designed for off-road use. Racing breaks are not recommended because mud and dirt can disrupt their braking ability.

Step 8

Purchase all remaining parts according to the build plan you are using.

Assemble the kart according to the build guide. This process may take a week or several months, depending on how much time you dedicate to the project and how prepared you are.
