How to Make a Track Go-Cart

Some go-karts can reach speed in excess of 250 KM.

Making a competitive go-kart for the track requires money, time and expertise. It is often an ongoing project, the kart is rarely finished and upgrades occur as better performance parts are produced. However, this doesn't mean that producing a track-ready kart cannot be done in less than a week. An expert knowledge of go-kart construction is required to get the kart ready. A track kart is significantly different than a fun kart that you see at amusement parks. Track karts are fast, competitive and dangerous for amateur drivers.

Things You'll Need

• Assorted tools
• Welding kit
• Chassis
• Wheels
• Tires
• Axle
• 250 cc engine
• Transmission
• Steering column
• Brakes
• Clutch
• Suspension
• Seat and harness
• Throttle and Brake controls
• Misc parts
• Body paneling

Instructions

1. Purchase a chassis. The chassis should be large enough to accommodate a 250 cc engine. The chassis should be designed for use in superkarts. This will ensure that it is strong enough for the track. It also will be a bare bones chassis and very light.

2. Purchase an engine. There are many different engine suppliers. A 250 cc engine is what is used on the track. They are either single- or twin-cylinder engines. If you are going to compete in a league, find out what engine restrictions they have. A used 250 cc motocross or dirtbike engine is a good option.

3. Purchase a gear box. The gear box should be a six-speed sequential gear box, designed specifically for high-performance kart racing. A standard gear box will likely break down due to the stresses of competition.

4. Purchase the wheels and tires. Check the requirements of the league before purchasing. Wheels are always racing slicks in good weather. Many racers have several different wheels and spares. Different tires are good for different conditions and tracks, hot and cold days and rain. Serious racers have a serious assortment of tires and wheels.

5. Purchase a suspension system. The suspension system is a vital part of performance. A good suspension can take seconds off lap times. The suspension should be adjustable and easy to work with. This is useful for different tracks.

6. Purchase body paneling. The body of the kart can be made from many different kinds of materials -- carbon fiber is best, but expensive. The body of the kart aids significantly in aerodynamics. It helps the kart obtain grip, corner and reduce drag. The paneling will include both front and rear wings.

7. There are hundreds of other parts that need to be purchased for the track kart. Consult a detailed build manual to determine what the best parts are for your specific kart.

8. To build the kart you need to set up a designated area where you can work. A clean garage is ideal. Consult a build manual to determine the correct way to build the kart. If all the parts are ready and you are working full time, the kart can be ready in about a week.
