How to build maps?

A young sports car is very popular among young car enthusiasts. It is called cards. But not everyone knows how to build the cards yourself. For real racing cars a special road surface is required, smooth and even. But, if you are not a professional racer, then you can build a house of cards that will drive along the roads.

Instructions on how to build maps

Tools and materials: metal pipes from magnetic materials; two-cylinder single-cylinder engine with air cooling; wheels; Steering Wheel; seat; pedals; gear; fuel tank not more than 5 liters; carburetor; shockproof means; shield for transmission parts; set of wrenches; hacksaw; welding machine. Now consider the manufacturing technology.


Before you start building a car, even the smallest, you need to know its technical characteristics. During the writing of this article will be given a small reference information on the technical characteristics of professional karts, sports and rolling.To build a home model, you need to know that the length of the map cannot be more than 1320mm, the distance between the axles can vary from 1010 to 1220mm, the diameter of the wheels - 350mm, the gauge size should be at least 2/3 of the wheelbase.

First you need to weld the base. It will be a frame that must be welded from pipes. Use for this only magnetic materials. Duralumin, carbon or titanium are not suitable. First is the front axle, then the rear. After that, the frame is welded entirely. The frame will be located engine, steering and seat.


For information: The engine in sports cards is usually located to the right of the driver (that is, in order to ride such a card, a heat-insulating pad is necessarily needed on the sleeve of the overalls); in the rental cards, the engine is at the back, which allows you to drive without any protective clothing at all, without the risk of getting burned. Fully equipped cards has a weight of 70-80kg.

You must purchase a motor. The engine will need a two-cylinder single-cylinder with air cooling. For operation of the map, no additives are allowed as fuel; only commercial grades of gasoline are permissible.

For your information: For a sports card, the power density may exceed the power of the car.The power of the entry level karts is 6-9hl. For sports karts, this figure will be 20-40l.s. All types of karts are subject to noise limits.

Brake system

The brake system will involve 2 wheels out of four, for control you will need an ordinary car steering wheel.

Depending on the class of the car, there are: mechanical brakes on the rear axle (it happens on rolling cards, as well as in children's classes); hydraulic brakes on the rear axle (in machines without a gearbox); hydraulic brakes on all wheels (in cars with a gearbox). Forbidden carbon discs.


  • Next you need to make a platform map. Its width should correspond to the width of the frame. The length of the frame will be the distance from the seat to the control pedals.
  • Install a fence that does not allow the legs to slide off the platform.
  • Install the seat. It must have a back so that at the turn of the rider does not shift to the side. It is imperative to use thermal insulation protection against burns, because next to it is located almost hot engine.


Close the transmission parts to at least half of the gear. For this you need a special shield.

There can be 3 transmission variants on the maps: in the lower classes of sports karts (mostly for children), the role of transmission is performed by a chain transmission. With the motor running, such a card should not stand; the engine will start in it from the pusher, the start is given on the fly. On some sports and rental cards: chain transmission and automatic centrifugal clutch. Most sports karts are equipped with a clutch gearbox.

Completion of work

  • Secure and close the fuel tank so that fuel is not ejected.
  • Slip steering and running gear units.
  • Install the carburetor. You can use both foreign and domestic carburetors and ignition systems. Anti-shock means are not prohibited.

I set out a brief information on how to build maps. She should help young car enthusiasts.

A little more information about professional cards, about their safety. The rear and front bumper, as well as the side boxes must protect the rider and the card itself during a collision. Fly off the chain to the side will not allow the casing, which closed the chain transmission. Cable duplicated brake thrust.In the map equipped with brakes, the rear and front contours on all wheels act independently, if one circuit fails, it can be braked by another. These measures allow karting to be a fairly safe sport, but we must not forget that this sport is still extreme, so it’s impossible to give a 100% guarantee of safety. Here the professionals described the process of how to build maps independently and attached drawings:.
