  Go Kart Frames-Choosing tektek the Right One for You 世纪互联 Karting enthusiasts emblazon the image of the perfect chassis in their minds: lightweight, yet powerfully durable material capable of launching a go kart forward without the slightest wear or tear. Rare material that comes with the likes of professionally built popular race-cars like the illustrious McLaren. What about karts that could rip through side turns at speeding bullet speeds without raising a wheel a centimeter above the ground, gliding tektek swiftly like a falco such as the futuristic cars in I, Robot? And along with perfect frames comes perfect tires, tires "grooven" to perfection providing the finest traction and downright freakish controls when running the curve. www.yahoo.comLet''s discuss the 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 the 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 the case of these speedsters, the 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 the backbone of earlier go kart planss and broke down easily. First off, simpler go- karts do not have the specifications needed (most important, suspension and tire traction) to ease the punishment frames go through while turning, accelerating, and stopping. Running on 2 or 4 cycle engines does not help compensate the health of a frame. A sturdy, well-built frame is the key to manoeuvring well on the track, especially when turning. Wait, isn''t a frame supposed to be resistant to the rigors and demands of punishing your go-kart as it explodes forward? Of course - but the 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 the track without sliding. Without the proper frame, go-karts will manoeuvre out of control, even shutting off in some cases due to over pressure to the engine. The design of the go-kart chassis has everything to do with how well it moves on turns and maintaining side bite. If the width of the rear rails (go-kart frames constitute front rails and rear rails) is narrow, with measurements ranging from 24 to 25 - from "kingpin" to "kingpin", the ends of the rail - it will have less tektek side bite. Wider rails barely ever exceed 30 on standard go-karts. Choosing the right frame for your go kart plans can largely depend on the surface you are riding on. Whether it is asphalt, concrete, or dirt - different types of frames behave differently according to surface. For example, dirt track frames should consist of a short front rail and a longer back rail. Dirt tracks place a lot of stress and challenge on the front rail and stiff back rails zipping through dirt can cut power to the engine while cutting a turn. The best frame for riding dirt tracks are ones with narrow fronts and longer backs, vice versa to asphalt and concrete. www.google.comThe A-1 performance of a frame largely depends on tire traction as well. Low traction tires (tires that do not "stick" well to the ground) are not grooved enough to withstand the rigors of the surface, rattling the stiff frame to oblivion. It also causes uneven weight transfer throughout the go-kart, and that is a no- no for maintaining optimum control of your money maker. Consider this scenario: you have two pairs of roller skates. One has wheels half-an-inch in width and the other has 3-inch-wide wheels. Which pair would provide better balance as you roller skate? If you love mathematics, treat traction as a formula with the equation: traction = stability. Go ahead, transform yourself into a karting aficionado with this valuable piece of knowledge! A major issue among karting enthusiasts is the durability and longevity of flexible frames. Exposure to punishing breaks and turns go kart, along with the gruelling hits to track walls every now and then, can distort the frame which cannot be "popped" back to its original condition.
