Go Kart Frames - Choosing the Right One for YouWritten by Michael Walker
Karting enthusiasts emblazon image of perfect chassis in their minds: lightweight, yet powerfully durable material capable of launching a kart forward without slightest wear or tear. Rare material that comes with likes of professionally built popular race-cars like illustrious McLaren. What about karts that could rip through side turns at speeding bullet speeds without raising a wheel a centimeter above ground, gliding swiftly like a falco such as futuristic cars in I, Robot? And along with perfect frames comes perfect tires, tires “grooven” to perfection providing finest traction and downright freakish controls when running curve.Let’s discuss intricacies and place a perspective on frames for your go-kart. The chassis as it is called in professional and enthusiast circles, is by far most important piece of this machine. The construction is paramount in maintaining a solid go-kart. What constitutes a frame? Think of a frame simply as parts holding a component together. In case of these speedsters, frame is welded together by torsion bars. Stiff frames are a result of shorter bars crossed together, and more flexible frames are associated with longer bars. Stiff frames that do not provide flexibility were backbone of earlier go-karts and broke down easily. First off, simpler go-karts do not have specifications needed (most important, suspension and tire traction) to ease punishment frames go through while turning, accelerating, and stopping. Running on 2 or 4 cycle engines does not help compensate health of a frame. A lack of traction on your tires will cause uneven weight transfer and stability on your frame, ripping one or both sides loose at same time. In essence, frame is responsible for determining how well your vehicle moves zipping on asphalt, concrete, or dirt – dictating your performance on wide turns and shorter turns. A sturdy, well-built frame is key to manoeuvring well on track, especially when turning. Wait, isn’t a frame supposed to be resistant to rigors and demands of punishing your go-kart as it explodes forward? Of course – but most important criteria for an excellent frame is to negotiate turns well. Frames are directly responsible for how well go-karts turn left and right. Weaker go-karts with cheap components are known to slide and drift along turns – in some instances, flipping to its side entirely with careless driving. “Side bite” is referred to keeping a go-kart planted to track without sliding. Without proper frame, go-karts will manoeuvre out of control, even shutting off in some cases due to over pressure to engine. The design of go-kart chassis has everything to do with how well it moves on turns and maintaining side bite. If width of rear rails (go-kart frames constitute front rails and rear rails) is narrow, with measurements ranging from 24¨ to 25¨ - from “kingpin” to “kingpin”, ends of rail – it will have less side bite. Wider rails barely ever exceed 30¨ on standard go-karts. The dynamics of front and rear rails can be effectively pictured using this example: suppose you had two bottles – a two-gallon jug and a 16 oz. Water bottle. Giving it a swift, hard poke to its side – which container has best chance of tipping to its side? If you guessed water bottle, you guessed right! Wider rails provide stability and “foundation” while turning, reducing side bite overall.

As big oil companies continue to grow bigger, foreigners are ones who get most of money. If you own a lot of oil stock you may be happy, but rest of us can only grumble when we see prices jump higher at pump. The gas station is easiest way to see how rising cost of oil affects us, but there are many hidden costs, too. Much of world’s oil now comes from middle east. We are able to see on a daily basis price of being dependent on another part of world for energy we have come to rely upon. The wars in that region may not be for oil specifically, but if there was no oil, there would be considerably less money to make war. Most of oil money goes to a few people who are in control. The majority of people in oil rich countries remain poverty-stricken and greatly resent way cash flow does not improve their lives. For every dollar we spend on gasoline or oil, a significant portion goes to companies paying taxes in foreign countries. In much same way that it hurts our country to lose jobs to foreign corporations, our economy suffers greatly when we buy foreign oil. The U.S. population consumes an incredible amount of energy. For most of us, mobility is necessary to live our daily lives. We drive to work each day; chauffer our children from place to place, and rely heavily upon rental and company cars for business travel. In a more perfect world, mass transit or bicycles would be much better, but with frequently changing jobs, nomadic lifestyles and hectic schedules, these options are hardly practical. Many people complain about price of gas, war and terrorists who are funded by oil money. Instead of enabling situation, let's make some changes for better.
